Pokemon Black and White Sequels Finally Announced

My Pokefever is now heating up!  Announced today by Junichi Masuda on the Japanese show Pokemon Smash is the latest installment to the long running franchise.  Contrary to the popular thought that a Grey version would be coming as has been the current formula of two titles and a third to wrap them together, this will be a Pokemon first.  A numbered sequel.  Two games entitled Pokemon Black 2 and Pokemon White 2 are due out for a Japanese release on the DS (not the 3DS?) this June!  No word yet on a stateside release, but one can't help but wonder what changes will come with this title.  Will it take place in the Unova region?  Will it be the same hero?  How will new Pokemon be introduced and will it offer anything new in combat?  Lastly, are those Pokemon pictured evolved states of Reshiram and Zekrom??  Can't wait to find out!  Stay tuned for updates!!
