(Update: 100 million mark reached!)Prediction:Switch will go on to sell 100+ million units

I don't think the NS will be "powerful enough to run most games" though.

It's telling that the demo video they chose to show Skyrim running on it (a upgraded port of a 5 year old game) and not The Witcher 3 or Fallout 4.

Why would they do that? Probably because the system can't really run The Witcher 3 acceptably.

It's a tiny portable form factor, it's not going to produce miracles, there only so much heat you can pump into an area that small before it melts even with an active fan. Not to mention battery life pretty much will cap off the unit at probably 10-12 watts max and that all cannot just be the GPU, the LCD screen, WiFi, CPU, etc. need access to power too. There's only so much you can do with 10-20 watts (docked) maximum. Even the Wii U itself consumes 33 watts.
