Well, I really hope that Mircrosoft gets their **** together. Their first party lineup consists of PS2 copys. Madden/Fever, SSX/AMped, Soul Reaver/Azurik, Halo/UT, etc.
With a few exceptions, Munch\'s and Malice, there doesn\'t seem to be a reason to buy an Xbox. MS really needs to create it\'s own path and show gamers it can offer something different so you don\'t have to get a PS2.
Nintendo, assuming they attend, will probably release a few details about GC, but blow the doors wide open on GBA. This will be exciting. They will probably save the GC stuff for E3.
Sony will show lots of stuff and leave little for E3 like they\'ve done every year. Very few suprises, but good ones.
Sega will probably just talk about it\'s rally of games coming out for different systems, leaving suprises for E3.
