It all comes down to the bread, and most of us can't bring out 600 out of the bakery at a time without suffering a horrible setback. Combine that with the fact that some of the PS3s(the cheap ones) willl dissapoint because they will not have the HDMI output and the fact that you are going to have to buy every single game at 60 to 70 dolllars, and that sucks.
Also if you buy the stripped down version of the PS3, you have no hop of upgrading to the Deluxe system, because they did not build in upgradibility. But the 360 on the other hand, can eventually be at it's deluxe even if you brought the stripped down version. Oh and then there is the GTAIIII matter, and all this talk that Microsoft is going to wrap it up exclusively and oh ****, that sucks for Sony.
