iPad 2 ads shot in New York last month?

9to5Mac reports that an ad for the upcoming iPad 2 may have already been filmed by David Sims, a British photographer, in New York last month. The iPads used in the shoot were all current generation models which will be swapped out with the new ones in post production.  A participant at the shooting, said that there were no new products on scene, and that everyone had to sign non-disclosure agreements. At this point, the only thing may be confirmed is that the new iPad 2’s will probably be the same size as the current generation iPads.
