Yeah, I knew 3D models of Pokémon was going to come eventually. Just from speculating Generation VI from way back before Black Version 2 and White Version 2, I could just feel that it would've taken too long to make RS remakes if they did it after Black Version 2 and White Version 2. And we knew that the developers would eventually stop developing new games in late 2012.
If they left out Pokémon Black Version 2 and White Version 2 and developed the remakes of R/S, then it would've fitted just as much as Black Version 2 and White Version 2 did, but they wouldn't have been able to make the sequels to Black and White otherwise.
But just thinking about the 3D interface... we could already see it had evolved in Generation V with the sprites and the 3D battle map. But as for the maps for towns and routes and stuff evolved in Generation IV. So yeah, I could very much tell that Generation VI would've provided something much more close to Pokémon Colosseum in regards to models.
As for Ninfeon, I'm thinking it could be Light-type... 'cause if you think about it, Light-type if it was introduced could mean two things: 1. Brightness. or 2. Weight.
