Great article! That's exactly what I've been saying all along and evidence points to this scenario.
As for power, Moore's Law indicates the following numbers:
Handheld: Quad-Core CPU clocked at 1 GHz, 1GB RAM
Console: Eight-Core CPU clocked at 1.8 GHz, 8GB RAM
Moore's Law points to a home console that's exactly PS4 / X1 level performance. Even doing the math for the GPU points to a card sitting snuggly between PS4 and X1 in power. I looked at past Nintendo consoles and handhelds and besides the Wii, every single console has followed Moore's Law. Nintendo does *not* ignore improvements in technology. They merely follow their own trajectory. It's highly unlikely NX will only be twice as powerful as the Wii U.
As for "gimmicks", I expect a return to Motion Control for the home console. The Wiimote 2 will feature sensors (heartbeat, etc.) and maybe something else. The handheld I expect to be a slide-open mechanic like the PSP Go but with a second screen: You can use the handheld smartphone style (vertically, with one hand), use it horizontally and slide it open to get access to the buttons and sticks. Simple as a smartphone, as complex as a handheld.
