I don't believe this thread has been created yet. If it hasn't, I dunno why it hasn't been already.
Anyway, I wanted to direct all of the Galaxy 2 thoughts/speculation into one wrapped up thread since it's been spreading to several threads.
First, I'd like to point out some the old-school bits (namely enemies) I've noticed in the trailer (besides Yoshi, duh):
-At 0:08, in the background you notice a rotating block resembling a ! or ? block at a 45ยบ angle. It has some red thing that resembles Bowser's face or something on it, then you notice a 1-Up Mushroom, and on the last side you see that it's a coin. Could that be replacing the Luma you have to feed 30 star bits to to get a 1-Up/Life Shroom or just a generic, random-item-spawning ? block?
-At 0:20, you notice that a familiar enemy has come back: Paragoombas. How freakin' awesome is that? There's more at 1:08.
-At 0:35, apparently that's Megaleg's little brother or something. That's cool.
-0:40 features the return of sliding courses as a possible shoutout to SM64's.
-0:46 reveals another familar enemy: Grinders from Super Mario World. That's very nice to see.
-Right at 0:59 (if you're quick) and 1:00, right before Mario freezes the water, you can see enemies that bear a striking resemblance to Skeeters that float on the water from SM64, flat-padded feet and all.
-1:26 shows the red & blue flippy platforms from.... wait, weren't those in Sunshine in one of the "The Secret of ....." levels? Also, you see huge ? blocks that have already been hit.
-1:34, it's impossible not to notice the SMB theme going on there.
-1:37, pause it right as Mario hits the third flower. In the top left of the screen, you see a ? block with wings reminiscent of Super Mario World's flying block.
-1:39, seems like Koopas might be common enemies instead of only being in a few levels. Also, that one's red! I wonder if they made them walk on all fours to make it easier to jump on them, or if they're trying to reference Mario Bros.'s shellcreepers or SMB/SMB3. The all-four walk is apparently being retained in SMG2.
-Lastly, who couldn't help but notice at 1:43 that you're Mario running on a planetoid of your own head?
So, yes, holy crap, I'm loving the old enemies/etc. that I've seen so far. We have Paragoombas from SMB3, Grinders and winged ? blocks from SMW, red/blue flipping platforms from Sunshine, sliding levels from SM64 and more of the SMB theme going on in the galaxies that resemble "The Secret of ...." levels in Sunshine. Friggin' awesome.
