There's just nothing on the road Microsoft is going down that I will ever be interested in, I don't think.
I've been very happy not having cable for years, I don't watch a whole lot of current TV or movies, I don't use Twitter and I try not to use Facebook, I have a phone that serves me very well for web browsing and such while I'm doing something else on the TV. Anything else cool on the system side is already being done by Sony or will probably be something they imitate later.
Combine that with my preference for Sony's first party franchises and developers over Microsoft's, and it looks like I might end up never owning an X1. But I guess E3 can make or break that, in theory.
I only paid attention to E3 2009 and later, which I think misses the 'amazing demo' window by a good 3-4 years. Uncharted 2 and Watch_Dogs were both hot, but not in a "Oh my God the future of games" sense.
