NES Remix too much for the 3DS?

In an interview with IGN, NES Remix series director Koichi Hayashida explained why NES Remix and its upcoming sequel will not appear on the 3DS. Apparently, hold on, it’s not powerful enough?

Yes. That was his reason. He explained he was already familiar with the Wii U’s architecture from working on Super Mario 3D World and, for that reason, felt comfortable developing¬†NES Remix on the Wii U. But then he said this:

“But, if you step out of the shadows a bit more, in order to accomplish what we wanted with NES Remix, and get the effect we wanted out of it and the value that we wanted it to have, we needed some more machine power.”

I know absolutely nothing about game development from a technical standpoint. And I also understand systems with different architectures can be very different to develop for. But to say you cannot make an 8-bit mashup game work on the 3DS seems like a thin excuse. I’m sure if they wanted to, they could make that version.

We could speculate on the real reason. Do they simply need more Wii U exclusives? The 3DS has been rocking it recently. Whatever the reason is, this was not the explanation I was expecting.
