Online Trailer Debut Delayed?

Coming Soon is reporting that the new Transformers: Revenge of the Fallen trailer "will come online today (Thursday) at 4:30pm Pacific Time!" This is 4.5 hours later then originally planned time of 12pm PST. A possible cause is Nelson's report of needed color correction. However, the delay also conveniently places the debut after E.T. will premiere the trailer in most markets.
