Hopefully Nintendo will come to their senses and hone the mighty power of the DS to make a new version of chrono trigger which won't mess with the story or gameplay, but more like a touch up like they're currently doing with FF III.  How about even a port of Chrono Trigger.

Super Metroid was an amazing game no matter what.  They should absolutely put it on the ds with a smart way of 3d side scrolling.  Same Idea as Megaman X8, but correcting all the flaws with the format.

How about a REAL, JUICY Lunar game which has voice acting, characters that make sense, how about the sequel to Lunar II?

The DS needs a good Animated RPG and I think another Lunar gamr done correctly will do just fine.

F-Zero DS would be incredibly incredible if they can manage the high paced controls without the stick.  Put it on Wi-Fi and oyu got yourself a sweet package.

Kirby Superstar +++

Kirby Superstar was incredible for SNES and if they were to add more to it with extra modes and even more new kirby games to it, new touch screen capabilities, Wi-fi match for the Arena mode, OMG it would be insane.

Super MArio All Stars +++

Same idea for Kirby.

Super Smash Bros 64 + on the ds with new characters and courses with online mode for tournaments and meele matches.  Also it would have to be a little better than the n64 graphics if they are able to do that.

A new donkey Kong for DS would be great, Like DK64, but with the old side scrolling aspect which made the game so original.

Band Brothers 2

this would be a great north american launch with more modes and songs.

Man I have so many other ideas, but I can't write them down all now, I have to think of more.!!!

DS will reign supreme..
