I remember seeing on reddit yesterday a link with Rockstar saying they were not targeting the next-gen consoles with GTA V, and the speculation around that comment was that the game likely would not be released for those consoles.

I don't know if I see a reason they should spend the resources to ship it for PS4 and XB1. They've obviously sold a few copies of the game already. I just can't imagine the market of people who want to buy it again or are holding out is big enough to justify the costs.

Edit: I'm a dunce. See the comment by adventured.

They've recently said they are going to release a PS4 version later in 2014. They refused to comment on the XBox One, interestingly.
