Pwned. Nothing "Official" then?
So Harmonix has not announced a keyboard, and it may not happen, but it's an idea that has been tossed around.
But what would be the over/under on a piano/keyboard peripheral?
That along with harmonized vocals seem like a pretty sure bet for a Beatles game.
Now, of course those two parts wouldn't be exported into Rock Band should the songs be exportable, but still.
The Beatles songs could have a one-time export, that allows you to play supported parts in Rock Band 2.
But to get the full experience, including keyboard parts, you would have to play the Beatles game, not the exported tracks.
Great Job with this as always
