Pokémon Black 2 & White 2 Info from Serebii.net~
The first images from CoroCoro have started to come. These images showcase the first screenshots of Pokémon Black 2 & White 2 and provide a lot of information. First, the game is set in Unova and shows the new trainers and the rival. The game is set 2 years later than in BW and features the map of the Unova region being partially frozen, while other areas have been updated, such as Route 4. The Unova Pokédex has 300 Pokémon within it. There are various new areas in Unova including Hiougi City (ヒオウギシティ), where you begin your journey. There are other areas which has a gym leader who focuses upon Poison; Homika (ホミカ), who is also said to be in the anime this June and sits in her gym which is a music club, fitting her appearance with a guitar. Another gym leader is Shizui (シズイ), the Water-type leader. The trainer with the spiky hair is the rival and there is a new researcher called Akuroma (アクロマ) who researches Pokémon Strength.
Hiougi City has a Pokémon Centre and a Trainer School and areas where you can look upon the areas. There are shops, underwater tunnels with clear glass (Mantine flowing overhead), building with blue and red statues all around Unova.
That's all the information these scans provide.
It has also been confirmed that Black Kyurem will know the move Freeze Shock and that White Kyurem knows the move Ice Burn.
Within the new Unova Pokédex, which contains a combination of old and new (Unova) Pokémon, Psyduck is #026, Riolu is #033 and Metagross is #254, with other Pokémon such as Tyranitar, Lapras & Arcanine being available.
