Not everything we're hearing about at E3 is so far off in the future: Mario vs. Donkey Kong: Minis March Again
will drop on the DSiWare store on June 8. If you need a reference point, it looks kind of like Mario vs. Donkey Kong
, but now it comes equipped with a level editor and you'll be able to share those online.
If your curiosity is piqued, you've only got a week to wait.
