Honestly, that was my second thought. Nintendo must have the strongest NDAs ever, because holy moley, there were a lot of people seeing that thing in the ad who said nothing about it.
Saw the full video. Like it, but the people playing just using one half of the controller... I need to try it myself, but I can't see how you could play something like an NBA game with just that, lol.
The whole playing games while on the plane though... that's really cool seeing how every time I go on a trip it tends to be over 14 hours...
