It's a shame the screening wasn't for a re-make of 2001: A Space Odyssey. You could have had the black monolith replaced with a Windows Phone 7 and have HAL the computer announce the start of the revolution (or would that be too 'droid like?).
So, what do you think? The ad is a teaser and void any substantive information on the new phones. It does match the desert theme of Lawrence of Arabia but for those not as familiar with the new Windows Phones, is it enough to spark an interest? It will be interesting to see what Microsoft does as a follows up ad.
