Transformers DOTM Filming in Cambodia?

This kind of came in under the radar. Back in January a member of Director Michael Bay's Shoot for the Edit forums by the name of EastwoodClinton mentioned an AKP article that stated Transformers DOTM would be filming in Cambodia in February. Cambodia's Minister of Information Khieu Kanharith even stated via facebook that he had given the "green light" for filming in the second week of February. Since then there's basically been no information regarding the rumored filming in Cambodia until this video was discovered on YouTube. The video shows a film crew at Cambodia's Angkor Wat Temple. The video is labeled "Transformer 3 - Dark side of the moon - took shot in Cambodia" and you can hear one of the onlookers mention "Transformers 3". None of the cast or vehicles are seen in the video, the only real action is a boom crane navigating over the complex. The YouTube member who posted the video commented that they filmed there all day. The AKP article mention earlier states they would also be filming at Bokor Hill Station in southern Cambodia.
