Looks like we might have information on when Grand Theft Auto 5 is coming out now. A polish website has posted this picture of what is supposedly Grand Theft Auto 5 ad that says to "Pre-order Now" with "Spring 2013" on the bottom. Now it does show the Xbox 360 symbol and the PS3 symbol but missing the PC nor the WIIU which could mean rock star is not making it for those platforms or will be released after the Xbox360 and PS3 versions.

Again this is all a rumor and could not be confirmed since R* doesn't usually comment on rumors. I'll be waiting for the game informer magazine to prove if it is legit.
