Super Mario 3D World looks better every time I see it, mostly due to the sheer variety of the level designs shown off in each new trailer. This new extended spot gives us quite a bit of new info, including enemy designs, and even a few boss fights.
I'm really looking forward to seeing if the character specific abilities, mountable creatures, and multiplayer aspects keep things fresh. It's just a shame that it has to launch in the incredibly crowded "end of November" spot.
As a side note, Nintendo Life has uncovered that the game will only take up 1702MB digitally. Not bad!
