Did Panasonic Make a Mistake Going Full Frame?

Camera Conspiracies:

I want to discuss whether or not Panasonic made a mistake by going full frame. Dividing your attention in two different directions never leads to us getting better cameras.

Was it a mistake for them to try to ask for a piece of the full frame pie when there is already so much competition?
