That was probably the best ad Nintendo's had for a game in ages. I hope the music in the game is as beautiful. I'm not a fan of cinematics pretty much at all these days, but Team Ninja seems to have created a remarkable style for the game.
Also, I didn't realize during my first viewing (I watched it three times) that they showed Mother Brain blasting the Metroid hatchling from the end of Super Metroid. Spectacular.
