I'm not sure what it is exactly about Scalebound's cancellation that caused everybody to have meltdowns and decide now is the time to naval gaze about the xbox platform as a whole, but the exclusive slate has not substantially changed since 3 months ago.
The last thread I remember reading about it seemed to be like 60/40 split as to whether it looked horrible or decent, in favor of the former.
By my reckoning, what the Microsoft slate is missing is one or two high profile, story driven prestige projects. Halo used to be this, but the industry's tastes changed and people aren't as excited about such an old franchise. What people seem to go gaga over come E3 are story driven games with great graphics. Ultimately, when people say "Xbox has no games" what it's really code for is "there is nothing in the same niche as Uncharted / Tlou / that new cinematic looking god of war". There is nothing blowing people away with animation quality that looks like it's going to make critics cry come awards season. Because in terms of games, there's definitely stuff coming out, the latest Gears was well received, the last Halo was well received, the Forzas continue to do well every year, there's some MMO water thing coming out, people are for some reason excited about Crackdown (if it ever ships), there's even a fucking RTS coming out. When was the last time there was a big console RTS? But even going back a year or two, the only thing filling
that niche, the one that gets people hyped, was a timed exclusive that just pissed most people off rather than getting them excited about the platform.
With Scorpio coming out, I think it's plausible that they're holding one or two cards close to their chest to act as "Scorpio launch titles", which will probably run a bit crummy on vanilla XBO but look stunning on Scorpio. But I doubt there's going to be much in the way of new AAA action adventure franchises with a strong narrative focus. I don't know if the Xbox team considers anything like that to be an actual high priority. There's definitely going to be new first and third person shooters, there's definitely going to be racing games, there's going to be fighting games. And they'll all be well reviewed, but for the most part the people here won't care much, because it's all pretty passé.
