I'm not sure, more power could mean anything. Maybe it's like a pc with a high performance mode using the dock and a balanced mode for the portable. Or maybe they are waiting to reveal the whole thing, there's a lot more to this thing. We don't know anything about the software, specs, os, games etc etc.

If it has touch screen it'll probably be for apps are smaller specific titles.

I don't think it will have a touch screen or a gyroscope or 3D or anything like that in order to reduce costs and make their games more accessible to developers. I think it's a good idea. Removing unnecessary and limiting features is smart. The Switch is the first Nintendo console (handheld or home) since the DS that I have not immediately thought "well, this is incredibly stupid."

But, what I am most interested in is this, something no one is talking about.
Nintendo showed people docking the Switch on the go to play local co-op in a plane or on a train. But because you're in a private setting, you can't play with sound. Thus, will the Switch have two headphone jacks?

lol

There is definitely the possibility, but it looks as if there are no more styluses.. maybe finger touch controls, or dropped entirely

It will have a touch screen, but I doubt it's going to be used in any game. Since games need to be able to play in either tablet or docked mode. Considering docked doesn't have a touch screen or pad. The chance of games having meaningful touch screen support is rather small.
