It looks like Nintendo is testing the mobile app waters with a new Pokemon app called Pokemon Say Tap? BW. Yes, great name. This app is a timing game that uses music and Pokemon cards with some tap action to make the first Nintendo game on a non-Nintendo mobile platform. That's pretty big news, folks.
The tapping begins this summer on both iOS devices and Android. An official date will be given later on the Pokemon site. The Japanese info page from Nintendo says that the game is coming to iPhone (3GS, iPhone4) iPod touch (3rd generation), iPad, and Android devices running Ver.2.1 or later.
This is really happening!
