Absolutely! I would love to have Animal Crossing New Leaf, and some other games as well.
Luckily, I have been able to play some titles (Kirby, Zelda OOT and LBW, Mario 3D Land, DKCR, Yoshi etc) with my brother´s new 3ds.

Yes. OOT3D and MM3D, luigi's mansion dark moon, kid icarus uprising, kingdom hearts dream drop distance and super mario 3d land.

Yes, without a doubt.

A 3DS player, that upscaled the graphics to 480p and supported 3D I'd buy in an instant.
If it's just ports, then I'd probably still get a few, especially the RPGs.

Yes.

I would've gladly bought Monster Hunter 4 for Wii U.

Yes. I would have bought some Zelda games definitely.

Yes, Kid Icarus Uprising with Wiimote support plz.

I do own the 3DS, but yes, I buy games because they are good, not because of what platform they were on.. (if I own that platform that is :p )

I wouldn't have bought games like 3D Land and MK7 since there are much better versions on the WiiU. Maybe I would have bought Luigi's Mansion, Kid Icarus and a couple of other games..

While I do own a 3DS that I hardly use, I would buy more 3DS games if they were available on Wii U.
