Apps the BlackBerry PlayBook can run?

I'm looking at buying a BlackBerry PlayBook and one of my factors is it's app line up. In particular in the android market. I know that BP now has the 2.0 feature but I still don't know what it has in store. Does anyone have a list or such with all the apps it has? In particular the android market?
What I'm really looking for is apps for learning Japanese. Most likely as an aid.
