What 3rd party developer is supporting the wii the most?

[Chrizum]

Sega maybe for their VC support, but otherwise it's laughable.

Capcom is the only third party that is currently taking the Wii seriously, and only mildly at that.

EA is trying, but meh.

Ubisoft has tried, but gave up.

The rest never tried and will hopefully suffer the consequences.
