No, I'm sorry, I don't know too much about the release of these products. However, I've been reading iPad 3 rumors (you can just Google "iPad 3 coming out rumors" or similar phrases) and it seems like it will most likely come out in March or April this year. Both the two other models came out around that same time.
It seems like the iPad might have a better camera, and have an A6 processor, so it would be super fast.
Hope this helped!
