Ok. My two cents:
--The Playstation Saga will never fail. They will be very prominent contenders to Nintendo. Their games are not "crap" as was so eloquently put. The fact that they pounced on the chance to take Squaresoft as their partner in making many of their games (Squaresoft is oh so da bomb) makes them a worthy adversary. The fact that Nintendo messed up by denying Squaresoft early on with their games (sometime after super nintendo) has really hurt them, but they persist, no doubt.
-- Xbox is going to crash and burn. They released it at a bad time after Gamecube and PS2 came out, ruining their chances for hype. It's like some guy making a decent entrance to a party right after a girl makes an extravagant one. Bad move Microsoft. And in addition to that, Japan isn't really that enthusiastic about Xbox. They see it as an inferior machine, and Japan and the US make or break any system. Other countries just go with the flow, but those two are the powerhouses and if one doesn't for it, it's toast. So overall, Microsoft made a decent machine but used horrible timing. Basically, stick to computers Billy.
-- Nintendo will live a long and happy life. If they continue making quality multiplayer games and adventuresome single player games, then there's no stopping them. Nintendo has pretty much had the monopoly on multiplayer (it's only contender being Dreamcast...let us never speak of Sega again...) and that gives it a good advantage over Sony (hey, of course I'm pro Nintendo. I just want to be logical in their superiority). Rumor has it that they've reconciled slightly with Squaresoft, which could give birth to FF games on the 'Cube. Overall, Nintendo is here to stay. Long Live Mario and The Mushroom Kingdom. Three Cheers!
--Ok, I know I said never mention it again, but what about Sega? Sega lost it a long time ago. True, they made a very slight return with Dreamcast, but in the end, it was overwhelming. Unless they are brewing an UBERsystem, their days are numbered. Maybe they can get a coffin with X-Box and get a deal or something.
