they dont come out here till early next year. i certainly won't be buying one right away, all consoles are stupidly expensive on release (i was the smart kid that waited 2 months to get my PS2 after my friends and i paid £200 instead of £500) i'll be doing the same with the PS3, waiting a few months then finding a decent deal somewhere.
PS3 rocks the socks of the xbox and the retarded nintendo. yes, i do hate nintendo, it's something about their camp characters and their underpowered crud (N64 was fun though).
PS3 is apparently very powerful, and from what i've seen in some reviews and a few TV shows, the graphics are smoother and faster than the other two. it's also one of the cheapest HD DVD players you'll be able to get in the next year or so.
but like nilsen said, i prefer PC all the way
