I'm not really sure that they are. They've overturned a lot of policies in the last few months but I'm not convinced they've overturned the overall ethos which has turned me against them in the last five or so years.
Are they going to be a console, for core gamers like me, for the lifetime of the console? I doubt it. Even if they do, can they do that better than Sony given the relative qualities of their first party studios and franchises? I really, really doubt that.
Look at what Sony has put on the PS3 this year (and is continuing to), and what Microsoft has put out on the 360. It's not even a contest. In fact, it's a bit of a joke. I don't regret getting a 360, but I do resent that the console has been giving me less each and every year. Xbox One has some really big franchises in its lineup, but aside from Titanfall I'm not seeing a great deal of real quality. Just to pick on Forza 5 - no dynamic lighting, no day-night cycle, no weather, and drivatars? I'm just not seeing it. Big franchise, big name, great graphics, but other than graphics, I'm not seeing the big leap forward.
To be clear, I don't think Sony's exclusive retail titles are any better, if at all. The digital stuff, and the future, is what interests me most. My interest in the PS4 is about The Last of Us more than it is about Killzone: Shadowfall. If Microsoft had given more over the last few years, and hadn't closed studios I loved (Ensemble Studios), and hadn't stopped games that I loved (1vs100), I might be able to judge this purely on launch lineups.
