I absolutely need:

Kid Icarus
Pilotwings
Star Fox
Mario Kart

I will wait to get my hands on the rest of the games, and then probably buy several more of them.  The 3D magic doesn't even cost much more to make, so I'd really like to see what some smaller teams can do with it in creative ways.

Definitely with most of the games announced.

I MUST have 3D Kororinpa. I want those balls in my face.

I am getting one at launch (hopefully). The games I want are a lot. I would list them but it is pretty much the list of games announced. I will know though around launch which ones I really want.

As the DS is by far my favourite system this gen, the 3DS is a must buy for me on EU launch day.

I'm mainly interested in games which are being developed for the system and not just ported, so at this point and out of the announced new games I'm only interested in Kid Icarus: Uprising and PilotWings Resort.

There's just one port I'm interested in and that's of course everyone's wet dream - The Legend of Zelda: Ocarina of Time.

I wil be getting at launch day. I'll be purchasing Resident Evil, Metal gear Solid, Kid icarus, and the Ocarina of Time remake.

I'll be getting one, probably a few months after launch. And i'll be getting all major Nintendo francise games. For other companies i'll wait for price drops :p

Absolutely. The lineup of games so far looks outstanding and I'm really excited to check out the 3D effects and the motion controls. The game's I will probably get so far are:

Mario Kart
Kid Icarus
Paper Mario
Pilot Wings (especially if it uses the motion control)
Assassin's Creed
Zelda OOT (I never played the 64 version believe it or not)

Maybe:
Star Fox
DJ Hero
Animal Crossing

Paper mario and that Atlus game for sure.

Depends on which games run on a Flashcard.
