Except Sega never had more than one really successful system. Anyone who really thinks they should go third party is just short-sighted, they will just have a slow downward slope and bring part of the gaming industry along with them. It's ONE system, guys. It's only been a little over a year now.

Its been down hill for decades, wii has a fad anaomoly.  Nin console sales have been droppin since the Nes.

So the Wii & DS & 3DS haven't increase in sells since the NES?
