It started off with the same stuff, but they slipped in another of those area-specific view screens of Tin Tower (with Ho-oh statues, and another Rattata!).
Then a egg hatching (pity they cut out), and then a nice shot from a lookout of some sort (maybe in one of those gates that appear by towns, or from the Radio Tower/Lighthouse (doubt the latter))? Text apparently has the person talking about Giovanni.
Then more overworld shots (old and new), wifi stuff that's already known or shown before...
Nothing new besides bits of video on the Pokethlon, more fancypants 3D special effect stuff... Then the Pokewalker - showed Kangaskhan being caught (and a Lugia being used) and also said one's parents can even use it XD:
Then interesting stuff. Route pics...
Cutscene with Kurt and Rocket Grunt by Slowpoke Well....
Jasmine battle sprite animation...(three Pokemon, yo, and a new green outfit!)
Then AWESOMELIFTOFDOOMINAGYMYAY - The Flying Gym got a makeover (but still 2 trainers and the same 'pattern' exactly if you ignore the lift). Still looks neat.
Then a view more things, with a touch more on Clair's gym, etc, and Ho-oh getting owned by Aeroblast. XD
Interesting that they had the Kanto Legendary birds flying when Lugia does, but might be just a reference to the movies? =/
More text to decipher - during Team Rocket's takeover of the Radio Tower! I wonder if that certain radio host from Crystal can be just seen there...
Then some more 3D effects... a shot of artwork..
The cutsey 3D thing with the Johto starters and Pichu was...well, cute. (And Pichu holding the leaf IMO was about how Pokemon follow you and give you items, perhaps...) Suicune random appearances around Johto now 100% confirmed - but interestingly, this strongly resembles Kanto (Cape by Bill's house). Extended storyline? Or maybe the vague chance it's just a redesigned area that happens to look like that? Not sure anything should be totally assumed on that, as of yet, but it certainly bears similarities, noting the trees and the pond, etc.
