It's definitely nothing I would take super seriously. He sounds like he's heard the same mix of rumors everyone else has, and he's trying to make it jive with whatever limited information he was given from people he knows.
The most interesting things here are that it's easy to code for and that people who have had their hands on it really do find it innovative. The home/mobile split in the software could be conjecture based on something he misinterpreted. It doesn't jive with what we've heard from Eurogamer et al.
My reading on the later posted info for the "game modes" for on the go vs. console, makes it sounds like two different power draw configurations. /shrug
Not sure where the ideas for Dreamcast/Mobile games are coming from, no one would do such a thing and call a system "easy to develop for", I'd call that a pain in the ass. Two different profiles linked to flipping a power switch? That I can understand and that would be much easier to work with.
