Band Hero is coming to the DS this fall. This may not come as a surprise to most, but the bundled drum peripheral just might. The rubberized grip fits over the DS (not the DSi) and allows for more comfortable drumming than just using the d-pad and face buttons.
The game’s executive producer, David Nathanielsz says:
They have this really nice push-back, bounce-back feel to them. They fit your thumbs well. If you start banging on that d-pad [without it,] you’d get blisters and you won’t have that feel.
Band Hero will also come bundled with the Guitar Hero peripheral. Up to Four players will be able to link up and play. No pricing information is available yet.
