Sony's doing an excellent job. The "few exclusives" they have (and they have quite a bit more than a few) are excellent, time tested excellent titles. Metal Gear Solid 4? Gran Turismo 5? Final Fantasy 13? I'd pay 600 dollars just to play those titles alone. Not to mention titles like Warhawk, UT2k7 (which, as I understand, will be fairly different for PS3 and for PC), Gears of War (yeah, it comes out on the PS3 too.) and the massive amounts of developer support they'll get for having the easiest console to develop for.
Not to mention a blu-ray player and a HTPC with an upgradable HDD.
