As much as I'd like to be, I'm not as excited about DS VC as N64 VC. Either the best games on DS have had updates/remakes (Pokemon, NSMB, Animal Crossing, Kirby Canvas Curse, Mario Kart etc), the games are already available (Chrono Trigger, the 3DS backwards compatibility) or the games are just not that great.
If they can get games like Contact, The World Ends With You, Radiant Historia, Elite Beat Agents and so on it'd be great but I doubt it considering it's Nintendo.
Compared to N64 VC with Wave Race, 1080 Snowboarding, Paper Mario, Excitebike, F-Zero etc DS VC is just not as interesting.
