Well, never is a long time. But I'm sure because it can't possibly make money, or sell consoles, on a budget that makes it worth doing.I'd like to know what makes you so sure.
Sly 4 is an unusual situation, and when it under performs, and GAF rips Sony a new asshole for not marketing it, people should consider the game never had to be made in the first place. Sony really isn't going to benefit, and most importantly, were never going to. Next-gen is going to cost more, Sony's big 'art' experiment with Team ICO has completely fell on it's arse. The time for indulging is over, it's all or nothing. They can't be wasting money, and mindshare, and release windows, with games of such limited appeal.
Ironically, I really thought we'd see an All Stars 2. I thought it'd be a next-gen $20 PSN thing, but I thought it'd be so cheap, and easy to knock another one out, and very fast considering the big titles will take a while, that I really thought it'd happen. So who knows. I could be completely wrong about Sly too, we shall see, I hope I am, the demo is slick as hell.
You didn't answer the question, but sure, agree to disagree sounds good./shrug I guess we can agree to disagree? If I love a game enough and it's an exclusive IP of a particular platform, I'll probably want to see something from it in a mascot brawler or party game, or w/e. I guess it really only works for Nintendo considering how easy it is to mix their IPs, and how lots of them are in the same universe.
