Actually, I don't think Generation VI will be a sequel to this generation in the same sense that Generation II was to its predecessor. The reference to N specifically notes that the region in question is far from Unova, so it's probably closer to the older regions.
I definitely expect to see N and Ghetsis again, but the generation that needs the evolution treatment the most is Generation III. Despite their large number, most of the Generation V Pokémon have decent stats and don't need evolutions, so I only expect to see around five evolutions added to the Unova family. Of course, that'd be akin to the treament the Generation III Pokémon received in Generation IV, and the Regis were the only legendaries whose story was expanded (via Regigigas).
So Kyurem could definitely be fleshed upon in the next generation, but I think it would be a lot more interesting and fitting if that happened in the Wii game instead. Let's just say the region north of Unova has a better chance of being the setting of the Wii game than it does of being featured in the next main series games.
