I didn't watch the entire thing, but from what I was able to catch, I'd say they only turned me off from buying it even more.
While there seems to be a bump in visuals, it's not enough of an improvement to feel like the next big step. Things ar better, sure, but those changes are pretty subtle, and I start asking myself whether it's even worth investing in a new, expensive system for seemingly minor upgrades.
They did try to showcase a wide variety of different types of games on there, which they obviously worked hard on. Most of them don't seem like system sellers though. I loved Demon's Souls when it came out, but what they've shown now doesn't look good enough to really get hyped over, and it's kind of sad anyway when your biggest release is a remake of an old game. Otherwise the game line-up didn't impress me much, but then I haven't ben a fan of Sony's output these last few years anyway. Might just be me.
The console itself looks horrible. It seems like it's huge too, so the ugly design will be difficult to hide.
