I am thinking about buying a PS3 for XMas since the HD-DVD wars went BluRay. An average BluRay player is about 169 to 189 so a PS3 console is just a small addition in cost. LBP was the second game I was blow away by when I saw it, since then the first game that blew me away on PS3 has a similar game on XBox 360 so I've yet to see any reason to buy the PS3 for it's games. With Dark Knight and Iron Man on BluRay I might just make the leap this year, I'll have to rebuy some of my movies AGAIN, which sucks.
I can't get me kids off of Spores, that game is amazing, I thought I was the shiznit when I mastered Age of Empires but this game starts at the single-celled-organism level and gets upto Planetary Empire Building before you even consider playing on-line. LBP will probably be the first game I buy if I get the PS3, I saw a demo of it last summer and was blown away, really cool looking game. Also looking forward to Halo Wars and Halo Recon.
