Regarding the new scan, here's some translated stuff:
http://www.pokebeach.com/
http://www.serebii.net/index2.shtml
Each has a tiny amount of information that the other doesn't, e.g. Pokebeach explains the logistics of the new attacks while Serebii gives names to some abilities that PB doesn't.
Regarding the GBA transfer...
Captain N said:
The Pokemon from the older games actually get transferred if you have Diamond and Pearl in the DS slot and either Pokemon Ruby, Sapphire, Emerald, FireRed or LeafGreen in the GBA slot. This isn't trading but outright transfer. Serebii.net seems unsure if the transfer is permanant, but if it isn't, then the obvious restrictions apply: transferring back only Pokemon and items that were available in the GBA games. Only 6 Pokemon per day can be traded, although I'm sure messing with the DS's firmware clock can remove that restriction. The features will probably be accessed after getting the National Dex in Emerald, or repairing Celio's machine in FireRed/LeafGreen. Ruby and Sapphire will probably work instantly. Likewise, something in Diamond and Pearl must be accomplished to read the GBA games.
The information has been updated by then--though, oddly, not on Serebii's site. He explained it in a news posting, but not in the D/P section itself.
Basically, all of the above is correct, but add:
-Yes, the transfer is permanent.
-When you transfer (not trade) the six Pokemon, they don't automatically appear in your box; they're put in a Safari Zone-type place where you have to recapture them. Thankfully, 1) they're the only things living there, and 2) they have some special Poke Balls with a perfect capture rate to get them again, so it shouldn't take long. Not sure why Gamefreak felt this was necessary, though, except maybe to "recalibrate" the Pokemon to check against AR hacks? They had no problem with direct transfer on Pokemon Box...
-You can't transfer another six until you've re-caught the first six.
-It's six per day per cartridge and per card, so... two GBA games could each transfer six a day to one game card, or one GBA game could transfer twelve a day between two cards, etc.
Edit: Also, as a sidenote...

3. Underground path (set traps, find the secret base, capture the flag)
4. Super Contest
It's funny to me, but just between these two things I feel like Pokemon is going to out-"Animal Crossing" Animal Crossing even
without the fighting. I mean, in ACWW the worst you can do to someone is plant a pitfall seed, not
set them on fire, and capturing the flag sounds better than fishing.
If D/P doesn't outdo ACWW for social mischief, chicanery, and house-building in a relatively confined area, the next Pokemon games will.
