"The Beta build of our Wii-U Pinball Arcade release will enter internal test next week. It is scheduled for final submission to Nintendo in late July, and for release to customers in September. All of the tables in Table Packs 1 through 16 will be available on the Wii-U at launch."
Another advantage to releasing TPA on a Nintendo console is that it may finally be possible to release the Gottlieb Mario themed tables. I don't know how the TPA people would feel about acquiring and digitizing the Mario tables, since Nintendo would probably mandate they be exclusive to Nintendo platforms. I for one, as a die-hard Mario fan, would love to play this table:

We are still working on it, we have not submitted it yet, stay tuned for a more detailed update.
