Not true. The 4 pillars are the minimum to make Nintendo fans happy.
An announcement of a Square Enix RPG or a big name 3rd party game would have done the trick too.
I remember the Capcom announcement for the GC. That did the trick. REmake, RE0, and RE4 all exclusive (or at least timed) for the Cube.

add me, the more the merrier.
