Iwata: Our next system will “absorb the Wii U architecture adequately”

people thinking the home console and the handheld will combine into one is ignoring what might happen if a system like that fails

Nintendo isn't stupid and it is very clear in what Iwata has said. the systems will be like brothers so how can brothers be in one body? in short there will be a handheld and a home console that will enable devs to easily port games between the two

This.

Iwata specifically mentioned two future systems - a handheld and a home console. Indeed, they'll share the same OS and will apparently get overlapping games released on them, but nowhere did he say they're scrapping the home console + handheld strategy. The contrary, in fact.
