New Macbook Pro form factor

Just wanted to start a discussion on the rumor that Apple is working on a 15" MacBook Pro with the form factor of the MacBook Air. This is really tantalizing to me and I don't see how I could resist jumping on board a product like this. Of course this form factor will probably involve compromises. What corners do you see Apple cutting to get this product launched or do you feel it will be as full fledged as the current MacBook Pro lineup noting that it will lack the super drive?
