As of right now, Wii has been consistently outselling Xbox 360 every single month ever since the console launched.
But Peter Moore, head of Microsoft's Interactive Entertainment Business division, recently questioned how long Nintendo Wii will be innovative and whether it's truly a next-gen contender.
When asked by 1UP what he thought about it, Moore was both complimentary and condescending at the same time.
"The same way when I first saw it last year: It's a very innovative device," he explained.
"It's done incredibly well at the holiday period and retailers seem to be very happy. The question that remains is, how long will the experience be innovative to consumers, and what are the legs of this thing? Is it a real next-gen contender that can continue deep into the lifecycle, that can continue to meet the numbers?"
Moore acknowledged that he does not own a Wii yet, but "I was hoping my friend Reggie [Fils-Aime, Nintendo's president and COO] would send me one."
