Wow! I wouldn't be surprised if Apple pulled that off. It would kill the market for any other type of "laptop" and send Apple's stock to the moon. The techology is available now and Apple has the capability to cram everything into a 1/4" thick unit.
Maight as well add it to the rumor mill. Apple could sendit out to feew testers disguised as a baguette, or a mailing tube, or a Pringles can.
