At least that's the main thing that's come out of this so far. Question is, what will this accomplish? Did they really need form changes? Thundurus is already OP, Landorus is fine as is, and... well, there's Tornadus, I guess. I dunno, I'm not that much of a fan of everyone and their dog getting alternate forms. Remember when it used to be special (it was a Deoxys thing exclusively before gen 4, in fact)? Oh well, let's wait and see, something good might come out of this. By the way, it's said they can only be obtained through the AR Searcher, which suggests that changing forms may be impossible. Throwing this out there: what if it's just a cosmetic thing, for bragging rights for those who bought the AR Searcher and were lucky enough to find these?
And while there aren't any scans to support this yet, allegedly a whole bunch of old characters will appear in BW2 such as Brock, Misty, Giovanni, Blue, Volkner, Steven and Lance. In what capacity would these appear, nobody knows. I sure hope they can be battled in the post-game, because quite frankly, BW1 was a little lacking in that aspect. Nonetheless, I remind you that this isn't confirmed yet, we could be dealing with a Trojan horse strategy where the leaker gives some accurate info, and attaches lies to it to make them sound more believable. I mean, why would the page with the genies be leaked, but not the rest? Sounds suspicious, but it could be true. More on this as it unfolds.
Edit: Pokébeach suggests that these might be female genies. Looking at their design, that's actually believable... but is the game code capable of handling something like that? If the new forms are assigned different rows in the Pokémon table, this is very much possible.
Edit 2: Speaking of Pokébeach, they're saying that according to the scan's leaker, every previous gym leader can be fought in BW2. As cool as this sounds, this doesn't sound like something Gamefreak would ever do. 40+ gym leaders in a single game? Seriously? Not to mention, we have yet to see any proof of any old character returning, at all. This is really, really fishy, and the likelihood that we're dealing with a Trojan horse leak just skyrocketed with that. Pics or it didn't happen. I mean, the guy does have a copy of CoroCoro, right? Why not upload the rest of the scans to prove that it's true?
