At a round table at E3 this evening Miyamoto was asked his feelings on the two projects.

Miyamoto responded with this

We try to have hardware and software developed and working before we actually show it to the public. We work hard on making our software and hardware accessible to everyone who wants to play it. It is our philosophy to plan development on hardware and aim for how software should work.

Pretty harsh words from Miyamoto, but I can see his point.
