More news: "Pokémon Black and White Versions will only feature Generation 5 Pokémon up until the player acquires the National Pokédex. In the update, Masuda said that his intention was to give players both new and veteran an equally new experience, akin to Pokémon Red and Green/Blue Versions back in Generation I." - so no Zubat's and Tentacool's everywhere this time.

Also, more pictures:
Team Plasma Grunts, they look a bit like knights:


The legendary Psychic/Fire Pokemon Victini, listed as #000 in the Isshu Dex:


And a few other Pokemon, apologies for the picture sizes, will try to replace them with smaller versions if possible:

More new Pokemon:



The "lady" one and the ghostly one are actually both Psychic types.
The eagle is a Normal/Flying type(no changes there).
The little dinosaur is a Dragon type.
The fuzzy bat thing is a Psychic/Flying type(as a counterpart to Zubat, maybe?).
The chipmunk is a Normal type.



And the piggy bank/tapir evolution is again a Psychic type. It produces Dream Smoke, which is described to hold the dreams of Pokémon, and allows you to upload your save file to the internet. A Dream World is also featured which allows you to obtain Pokemon not native to the region.



Friends/allies of the main character above.

And a mysterious rival/antagonist who apparently "wants to split humans and Pokémon and divide them to create a black and white world. He has the unique idea to set Pokémon free from people, and looks for the power to bring his idea to reality.".

Finally, some confirmation of version specific locations(as I suspected when they said there would be more version differences than just the Pokemon), namely, Black City and White Forest:

What a simply perfect and beautiful article.

So, the Pokemon Sunday host spoiling Zekrom being Dragon/Electric was right after all. Seems there's also a nature vs technology theme then, possibly. I wouldn't be surprised if there's a third legendary that's Dragon/Ice, either.

As for the other news, it's nice to finally have a female Professor, and I'm liking the Daruma Doll/Ape and Pigeon the most, I think. Though the Piggy Bank looking one is interesting, and the Chinchilla is cute... if it's another Pikachu-ish one, at least it looks rather different, like Marill, and unlike Plusle/Minun and Pachirisu(different type, too).

Update: Reshiram and Zekrom are at least part Dragon type.

Bulbanews: "Also, they have mentioned that there will be a big difference between the two versions, aside from the version-exclusive Pokémon and encounter rates."

Superb. About time too.

Yes, the white legendary, Reshiram is on Pokemon Black and the black legendary Zekrom is on Pokemon White. Makes a nice contrast that way. They both have a 'have a strong connection to the history of Isshu(the new land) and are key to the games' story', no surprises there.
