Correction: shiet, you philistine

Moore's dead on with his prognosis. I'd definitely buy a 360 and Wii before a PS3...even now, I have a Gamecube and Xbox. Though the only reason I got the Xbox was to hack it and burn games. But that's neither here nor there.
I'll put it this way: 3DO looked better than Genesis, SNES, Turbografix, et. al. when it came out, but it failed for one very big reason: IT COST $700 AND NEVER DROPPED. It was just too expensive to make and market. And there were no games...it was marketed as a media machine, which meant lots of Sega CD-esque FMV games (albeit in decent resolution), no variety, and, after weak sales, no incentive to code new, better games. Hell, ports were rare for that machine because of the weird-ass hardware.
Sony is pumping out the development kits and signing up exclusive title rights and burning the midnight oil to make games that will induce consumers to take leave of their senses and mortgage the house to buy a PS3 in the first year. But given the high early costs, the absence of any real killer apps, and the very high manufacturing costs, they're going to have to hope God's a Playstation fan to make this work out.
