New Pokemon Game Announcement Coming in May?

Word out of Japan is that there will be an announcement this May for a NEW Pokemon game. Pokebeach broke this story a few days ago, speculating that it could be the next Pokemon Battle Revolution, the first Pokemon 3DS game or something else??

I believe that we will get an announcement next month (it fits with the timing of B&W being announced last year) with the first public showing of this game probably happening at E3 in early June. Below is the page from the above magazine that shows the first screen. I have to say, from the size of that screenshot, it looks to be a portable game

What do you think/hope it will be??
