The fact of the matter is that the Wii is basically dead at this point. WIth only a few quality titles gracing the system last year, and virtually no exciting games on the horizon, it is clear that Nintendo is putting all their eggs in the Wii U basket. In fact, Nintendo basically went so far to say as much in a statement accompanying their reported losses.
"While [Nintendo] did post a loss for the recently completed fiscal year, the continuing momentum of the Nintendo 3DS and the global introduction of the highly-anticipated Wii U home console will drive the company back into profitability in the current year."
Will the Wii U really be big enough to pull Nintendo back on its feet? They'd better have one heck of an E3 press conference planned if they hope to get out of the red this year.
