Wii popularity bubble about to burst?

Japanese business paper The Nikkei recently published a piece titled Software Houses Miscalculate Audience, Demand For Wii, wherein author Tomoyuki Kawai cites that many inside sources are not looking to the Wii with such a favorable eye any longer. The big worry is that all of this success the Wii has had has only benefited Nintendo and them alone, with many third-party developers jumping on board only to be left with titles on their hands that failed to sell. It's these development studios that are supposedly not profiting compared to their previous year earnings, the result being a lack of support for the console and no desire to commit to it in the future.

The piece goes on to say that a lot of the Wiis picked up by consumers have only started to gather dust (it's unconfirmed if this is the same report we've posted about here earlier).
