I bet it will. The secondary thing with the DSi which they foolishly never advertised was the double speed CPU and 4x RAM on it. A good many games, some pretty decent ended up using that. I happened at the time to have the Sonic genesis emulation package for it and both models of DS handy and man was there a difference in the smoothness and speed of the Sonic games on the ungimped DSi hardware.

If they really do use all that added room I mentioned is possible in the other thread if they maxed out the existing hardware and upped the ram they could do a lot. The thing is they really need to advertise the crap out of the beefier specs, the clean 3D at wide angles, the Amiibo internal support, all of it, not selectively and it'll help.
