Yep, so then again useless babysteps. They'll be basically doing what Sony did with PS3 and Vita. To be fair, I think they shouldn't even care about specs. It's not like they cared with Wii and Wii U. They should just be like: "Allright we're alone, so we'll just have the same scalable architecture for our hardware"
They could have either both handheld and home console with x86 or ARM. Just run the handheld games at 480p and the consome game at 1080p. That should do the trick. As for the horsepower, you can already get better performance than Wii U in a handheld.
Considering how Iwata specifcally used iOS and Android as examples of what they would like to do, I suppose there are high chances of seeing the "Nintendo ecosystem" you just mentioned.
