The games will be available on the Nintendo DS in autumn, following the Japanese launch in June.
Announced over the weekend, details remain thin on the ground, although the Legendary Pokemon featured in promotional posters (above) have been identified as the Black Kyurem and the White Kyurem.
The games' launch will mark the first straight sequels in the core Pokemon series. Nintendo traditionally distinguishes new additions to the franchise by colour, rather than numerically.
Nintendo had been teasing the reveal for some time, though the new game was expected to be Pokemon Gray for the 3DS.
Pokemon Black and White 2 can be played on the Nintendo 3DS, but without any additional 3D effects.
