I've always liked Yoshi's Island. While I haven't played the DS one (always thought it was a port of the GBA/SNES one without really looking into it), I think the new one looks pretty great. The art style stays true to the original and still manages to have a lot of improvements, and the gameplay looks like much of the same (which isn't a bad thing, since it's not bland like NSMB)
Definitely grabbing it when it's released.
