I probably won't buy the 3DS first day but I definitely will be buying it eventually. Also, I can't wait for Mario Kart 3DS! Oh yeah!

I was gonna get a dsi til I found out about XL. I waited a bit until XL came out then I hear about this. They should have just made this in the first place!
I might get this but it depends on 3 things:

Cost
Release date
How much it has improved from the XL. If its a minor improvement then no.

The 3D part is getting me interested though.

I voted no, because i usually buy a console or handheld only a year and half after release.

I won't get one until a game come out that I really want.

Any of these would work (plus maybe something totally original that I never thought of)

Mario
Zelda
Metroid
Professor Layton 3DS exclusive
Fire Emblem
Advance Wars

However, I will be at the store shortly after it is released just to try it out.

Yes.

I definetly would buy the 3DS but not at launch.

Day one for me! (If I can afford it.)

i will wait unless there is a game i really want on it

Not until it has the games that I want. Also if its bulky I'll wait for the lite version. Though I won't buy a DS that has no good games at launch. Just wait.

I'll get one with (hopefully) New Super Mario World and F-Zero 3DX.
