I just noticed now that unlike Zekrom for White and Reshiram for Black, Black Kyurem is representing Black 2 and White Kyurem is representing White 2. Hmm.
Considering that these are labeled "Version 2", I'd say it's very unlikely that they'll be similar to Crystal, Emerald, and Platinum. N vanished on us and Ghetsis got away, so they've already set the stage to continue their stories. This could actually be a lot more interesting than I initially thought.
What I'm hoping to see is that these games act both as plot sequels but still add a bunch of new content like our typical third games do. Give us something akin to the Battle Frontier, allow the Gym Leaders to be rechallenged at higher levels, add a new location on the world map to explore, fix our WiFi issues, add more wild Pokemon to the region pre-National Dex, etc. I'd also like to see Pokemon appear outside their PokeBalls again and the Entralink be extended to WiFi (even if it's very limited WiFi).
Lastly, I think Black and White Kyurem look snazzy. Masuda called them "new Pokemon" but I doubt that means what people think it does. I can't really see these two receiving their own PokeDex numbers for example. My theory so far is that they merged with the Dark Stone and Light Stone, but I'm intrigued to find out the full story. Won't be long~
