Transformers 3 in New York?

For the last few weeks, Transformers: Dark of the Moon has been filming in Los Angeles and now it seems that production may move to New York City, at least going by a possible casting call for the movie. From On Location Vacations:

Grant Wilfley Casting is seeking the following for background work on TRANSFORMERS 3: the Dark of the Moon:

* Arabic/Middle Eastern, South Asian/East Indian, and African men and women with traditional ethnic wardrobe for work on Nov. 12 or Nov. 13.

Email a recent picture and contact information to casting@gwcnyc.com. Write the role for which you are submitting in the subject line of your email. Filming the week of November 8 in NYC.

This is a different casting company then used for previous extra calls. Usual caveats about scams and the like with the biggest being any requests for money makes it a fraud. Maybe it is a quick pick-up scene but highly doubt it is a major sequence or they would have fit it into the schedule when moving all the Transformers vehicles, pyrotechnics and the like all over the country when filming during the summer. Gearing that up again would be very expensive making the standing NY set in LA a better alternative if a large scale action sequence was needed.
