I'm jealous of ZombieU and a couple of the "launch window" games, but buying a new console at the moment really isn't a consideration for me. I always wait till a library is on solid ground, anyway. I've never bought a console at launch. The tipping point for me is usually when the system has several excellent games plus a few masterpieces.
I've had two experiences with brand new consoles that really stand out for me. The first was the PSOne and Final Fantasy VII. Obviously, at the time, it just blew everything away and really redefined video-games. The moment I saw the FF VII commerical, I was like, "OK, it's time to get back into gaming."
The second was the PS2 and Gran Turismo 3: A-Spec. I was already a big fan of the series from the first two games but GT3's intro movie left my jaw on the floor and got me really, really excited. It just clobbered everything at the time.
