SQUARE ENIX
Square Enix's E3 conference is one of the most highly anticipated of the show. Sony's recent State of Play event showed new footage from the Final Fantasy VII Remake, which concluded with a message saying that more information is coming in June.
- The Final Fantasy VII Remake announcement at E3 2015 is considered by many to be one of the best moments in the history of the conference, yet almost no new information has been revealed about the game since. If Square Enix is finally ready to show the game again, then it's possible that a release date might be forthcoming.
- The other big title that has been announced for Square Enix's E3 press conference is Marvel's Avengers (formerly known as The Avengers Project), which is a game that is being made by the teams behind the Tomb Raider series and the recent Deux Ex titles.
- One title that has been rumored to appear at Square Enix's conference is Collection of Mana, which is a name that was recently trademarked by the company. The name seems to refer to a localized version of the Seiken Densetsu Collection, which is a Japanese-exclusive title for the Nintendo Switch that contains the first three Mana games.
UBISOFT
Ubisoft has confirmed that its E3 pre-show will contain updates for games that have already been released, including Steep, For Honor, Trials, and Assassin's Creed Odyssey.
- The main Ubisoft conference is confirmed to feature updates about The Division 2 and to have more information about the upcoming Ghost Recon Breakpoint. The post-show will include a celebrity deathmatch in Rainbow Six Siege, which suggests that more information about that game will also be coming.
- There are also rumors that a new Splinter Cell game is in development, as well as hints for Watch Dogs 3. Ubisoft has confirmed that there are no new Assassin's Creed games due to be released in 2019, but they could still promote a 2020 title at E3.
NINTENDO
Nintendo will be holding the last press conference at E3 2019 with a Nintendo Direct. It's been somewhat customary for the annual expo to have Nintendo deliver a presentation the morning of day one.
- Nintendo is also hosting tournaments for Splatoon 2, Super Mario Maker 2, and Super Smash Bros. Ultimate throughout the event.
- The Nintendo Direct is supposed to be focusing on Nintendo Switch games that are due to be released in 2019. There are rumors that the focus of the Direct will be on Animal Crossing, which is one of the Nintendo Switch's biggest games of the year, yet almost no information has been revealed about it so far.
- There are two games in The Legend of Zelda series due in 2019 - Cadence of Hyrule and The Legend of Zelda: Link's Awakening, which will both almost certainly make an appearance.
- The second DLC character for Super Smash Bros. Ultimate will likely also be revealed at E3, with different leaks claiming that it will be a representative from the Dragon Quest series.
- Pokémon Sword & Shield will have a separate Direct that is focused on them a week before E3, but the games will still likely appear at the event.
- Bayonetta 3 was mentioned in passing during the February 2019 Direct, which suggests that the game could appear at E3, as almost no new information has been revealed since its announcement.
- There are several new games that are due to be released over the next coming months, such as Astral Chain, Luigi's Mansion 3, Marvel Ultimate Alliance 3: The Black Order, and Super Mario Maker 2, that are all likely to appear at E3.
E3 COLISEUM
Not every game at E3 will be featured during press events, as other developers will be hosting events and streams following the Nintendo Direct. It's possible that these games might also appear during other conferences, but they also have special streams that will take place from Tuesday, June 11 to Thursday, June 13.
- Borderlands 3 is confirmed to be making an appearance at E3. The loot & shoot game will be taking the series to the stars, as the player will be able to leave Pandora and explore new parts of the galaxy in order to massacre the inhabitants and steal their gear.
- Techland will be showing Dying Light 2, which is a survival horror game set in a city following a zombie apocalypse, where the player's choices will determine the fate of the environment around them.
- Netflix will be hosting an event called "Bringing Your Favorite Shows To Life: Developing Netflix Originals into Video Games", which will almost certainly feature an appearance from Stranger Things 3: The Game, especially as the show is due to return in July and the game is intended to be a tie-in.
- There is going to be an event based around the upcoming Psychonauts 2 which will feature Jack Black. The game was funded on Fig back in 2016 and the game is finally due to be released this year. The original Psychonauts is a platform game that has accrued a huge cult following, which is why it had to wait until the advent of crowdfunding until a sequel could be made.
- A Darksiders event is scheduled to take place at E3, which is meant to end with a reveal for a "brand new Darksiders game that takes the franchise in a fresh direction", which means that Darksiders IV is a safe bet for an announcement at E3.
- The last game to receive its own event will be Ancestors: The Humankind Odyssey, which is an upcoming third-person survival game that is set in prehistoric Africa.
