There's something new in regards to the Wii: WiiWare.
"Independent developers armed with small budgets and big ideas will be able to get their original games into the marketplace to see if we can find the next smash hit," says Nintendo of America President Reggie Fils-Aime. "WiiWare brings new levels of creativity and value to the ever-growing population of Wii owners."
On the Virtools site the WiiControler AddOn Pack is already present, like the PSP Controller (btw. why are both extensions called controller?). But Virtools is not alone, also Unity3D is porting their engine to the Wii. Which one is going to be the better deal?
