I don't know why, but my guess has to do with being able to hook a hard drive up to them for reasons I think that are not supposed to be talked about here.
I'm wondering if someone would pick me up a PS2 or if they have not opened theirs yet, sell it...? I can't find a new one, I really want one, and if I can't play Final Fantasy X and finish Summoner soon, I'm going to go nuts!
