Ubisoft has recently taken up the role as a major third-party cheerleader for Wii U, and in a recent interview with Reuters, the company's CEO Yves Guillemot continued to talk up the system and its launch prospects. Guillemot had this to say about his expectation that Nintendo will manufacture five million Wii U consoles in its first six months, and argues that his company's support for the console isn't a major risk.
Generally, that's what (Nintendo) does. The number can be more, it can be less... they are always limited in the number that they can build.
It’s easier at the beginning of the console cycle to astonish people and bring them new experiences than at the end of the cycle. So the risk that is seen as a big risk by many is actually the contrary.
With Nintendo's latest financial reports estimating 10.5 million combined sales for Wii and Wii U in the fiscal year, that estimate of five million units may not be far from the mark. Will the console be a success and lead to stock shortages like in the early days of Wii? We'll have to wait and see.
