Engadget posted a picture that was grabbed off of a German online store that looks to reveal the packaging of the Microsoft Arc Touch Mouse. The arched mouse, if this is indeed it, looks like it folds up similar to the Arc Mouse (which I like a lot as a traveling mouse) but obviously it would have a multi-touch surface to go along with that portability.
Again, nothing official on this but it looks like the price is scheduled to be around $69.
