Guitar Hero DS

Can't wait.

There were some proof of concepts posted on Kotaku a while ago, the controller looked a bit weird but the concepts were made by fans I believe.

Personally I love rhythm games on my DS.

Osu! Tatakae! Ouendan! For the win (or Elite Beat Agents for the US people).

nice, looking forward. I myself am working as a 3d modeler for NDS.
