I know there is a big 3DS thread but that is more about the hardware. If these needs to be merged though thats fine. I've ordered a 3DS myself even though the launch lineup leaves me cold. But Raving Rabbids: Travel in Time 3D is out on 1st April so that isn't too long to wait.
I really like 2D platformers and this is what this game looks to be. I know it says 3D in the title but it is a traditional 2D platformer with 3D elements. There isn't much information out there on the game but the trailer looks good. I'm hoping that reviews will be good, if so will likely be the first game I buy for the system.
