Well, Masuda kept his word, there was a surprising Pokemon announcement on Pokemon Sunday…
At the end of the show, he revealed that both Black 2 and White 2 are currently in development for the DS. The games will see release in Japan around June, which in turn will more than likely translate to North America in December and Europe in April as per the norm.
It has also been confirmed that the games will indeed play on the 3DS in 2D, no 3DS exclusive features have been confirmed.
This announcement was quite unexpected as most were putting their money on Grey for 3DS.
