I really like the fact that HVS is actually trying to push the Wii's hardware, both because, I mean, it's just good in general, but more developers can actually see third-party success. I have been keeping my eye on third-party developments for both Wii and DS, and both are showing more third-parties trying. Just providing a list

:
Moon(DS)
Dementium: The Ward(This one actually came out a while ago)(DS)
World at War(Wii)
Deadly Creatures(Wii)
MadWorld(Wii)(Thanks Maxi)
Soul Bubbles(DS)(Thanks Maxi)
