I remember there being the Crystal modchip, Infinity, New "Messiah" team chip (Forgot what the name was.....

). I forgot if there are any more coming out.... perhaps a DMS? Anyway, I don't believe there will be HDD support for the PSTwo. USB ports are too slow to stream games. Also too many issues right now with the first batch of PSTwos, I've heard some "blow up" or the laser fries and such. AFAIK..
