The company has revealed that while the game was originally intended for a much earlier release sometime this spring, the delay was necessary in order to polish the game up.
A statement reads, "We know this is about four months later than originally planned and we know that this short delay will come as a disappointment to many of you, but, trust us, it will be worth the extra time. GTAV is a massively ambitious and complex game and it simply needs a little more polish to be of the standard we and, more importantly, you require.
"To all Grand Theft Auto fans, please accept our apologies for the delay, and our promise that the entire team here is working very hard to make the game all it can be. We are doing all we can to help ensure it will meet if not exceed your expectations come September – we thank you for your support and patience."
No reference is made to the rumoured PC and Wii U versions of the game so, if you're hoping to play the game on a platform other than PS3 or Xbox 360, it looks like you may have to keep waiting that little bit longer.
Given how Rockstar's previous big titles like Max Payne 3, Red Redemption, L.A. Noire and even Grand Theft Auto IV have all launched in spring, we reckon it's safe to say this decision definitely wasn't planned. It's a bit of a pain, but surely the delay is justified if it'll help the game live up to the massive hype surrounding it? Let us know your thoughts in the comments.
