Why would they ditch the wii?

The WW sales of the wii are far enough ahead to suggest an exclusive wii title would sell more on nintendos console than the competition

Install base for multiplatform PS3/360 games is higher.

 

Say that to this article:

Tell what to a fact? A completely unrelated fact? Is it higher than PS3 and 360 combined?
