There's some new WiiWare games on the way. Like some pirate ship themed battle game and a Wild West onrails shooter that uses the Wii Zapper.
I've read theres about 100 or so more WiiWare titles in the pipeline but I can't find the story online right now.

And sadly, like retail Wii games, only a couple will actually be good.

I think that pirate game is available in North America, but it probably sucks and I've ignored reviews about it because I know it's going to suck.

Might download Bomberman Returns when it hits WiiWare. It's going to have the option to play as your Mii, change outfits and have 8 player online battles.
