To break down the new SMG2 trailer:
0:00-0:12 - The game's logo has changed a little. You know what else has changed? The music is fully orchestrated. Thank you, EAD Tokyo.
0:13-0:15 - Graphics looking as good as ever, possibly better than the first game, though it's hard to tell.
0:16-0:18 - This platforming concept was in the E3 trailer, but it still looks cool.
0:19-0:33 - Drill item in action again. It can both go through the planets and burrow inside of them for secrets. The boss seems to bear a resemblance to Megaleg.
0:34-0:44 - That dragon is really big. It reminds me of Fracktail from Super Paper Mario; I wonder if you can climb around on it.
0:45-0:52 - Dry Bones and Boos are messing with the ground you can walk on. Looks dangerous.
0:53-1:22 - It's Yoshi! He can flutter. He can turn orange and run fast. He can turn blue and float. His tongue appears to have quite a few functions, including grappling and pulling objects. The pointer seems to be used to aim the things Yoshi has swallowed as well (like firing Bullet Bills into a giant mech). And hey, it's Bowser Jr, back for more.
1:23-1:35 - Everything is really big. The angry Wigglers in particular are very menacing when enlarged. Good to see some more 2D sections.
1:36-1:49 - Gravity puzzles are being taken to the next level, from the looks of things. Did you see the crazy gravity on that cylinder? Brain-bending.
1:50-2:05 - I'm not sure, but it would appear that Yoshi may actually stay with you after completing a level.
Must. Have. Now.
