New Nintendo Direct - 21/04 - What do you expect?

[gumby_trucker]

So what other mega-sellers from the DS have Nintendo not announced sequels to on 3DS?
We've got Nintendogs, Mario Kart, Brain Training, Animal Crossing and now 2D Mario.
Is there anything left?

edit: I would also like to add that so far, based on impressions alone (don't own a 3DS), many of these seem to be very similar to their predecessors.
