Will the HUMMER HX concept appear in Transformers 2?

I had my issues with last summer's Transformers movie, as did some others, about the missed opportunities for green vehicle placement. Remember the HUMMER HX concept from Detroit earlier this year? Looks like it might be the biofuel beast to beat in the sequel. Even as GM considers ditching the HUMMER brand, some spy shots (apparently taken by someone called Marceli over at Releaselog) of the start of filming revealed the vehicle above on the set. Authentic? I have even less of an idea than you do, but speculation is running rampant all over the chat rooms about what the HX is doing there. Does it say NEST or NERT? Would it be for humans to drive or is this a new robot thing? We're sure to hear more as time moves on, but one things for sure: that's a HUMMER HX all dressed up for something.
