The 1st unit involved in production of Transformers Revenge of the Fallen is on a 4 week hiatus due to Shia LaBeouf's hand injury. The the second unit, (the team that shoots footage which is of lesser importance for the final motion picture, as opposed to the first unit, which shoots all scenes involving actors, or at least the stars of the film) is still filming. Second unit footage typically includes shots like scenery, close-ups of objects and other inserts or cutaways. There is currently no indication that this delay will effect the release of the film.
