It all depends on how developers take advantage of the technology that Nintendo brought to the table. If they release the online component like they promised, then NO... the Nintendo will definitely NOT be a failure. If they hold back and continue to promise but do not deliver, then I see a dark fate for the Wii. As of right now, I see an extremely bright future for this innovative console. And let's face it, there are enough Nintendo fans out there to keep the Wii afloat even if the skeptics turn on it. Can you say Gamecube? That would have been the next Dreamcast... but Nintendo fans are passionate and kept it just alive enough for Nintendo to attempt another console. And quite frankly, I think Nintendo struck gold this time around.
