What's different about that deco? Could it also be that they just tweaked another ship in Photoshop as to not photograph another fighter?
The photo Nick posted is pretty much the same one that EE had on their site a few weeks back (and which I mentioned on 10/21/2007 earlier in this thread) for the Obi-Wan JSF. And, as Brian mentioned a few posts earlier, Hasbro said in a Q&A that the photograph was a mistake of some sort and that the ship that would be released would be identical to the 2005 TRU exclusive and *not* this (film accurate) repainted version.
For the record, the main difference in the two is that the original Utapau JSF was a brilliant white with blue accents and (as I complained about endlessly at the time) came with an incorrect sticker sheet (of Anakin's yellow JSF). In the film (as in the Titanium 3" vehicle), Obi-Wan's JSF he took to Utapau was silver/gray with blue accents (as seen in the photo Nick posted and that I linked to on EE's site earlier in the thread). I'm hoping that, regardless of which version they go with for the actual release, Hasbro sees fit to at least include the correct sticker sheet and not Anakin's yellow JSF sheet like the original release.
(For the record, Hasbro did eventually send out replacement corrected sticker sheets free of charge to most people who complained on their site, but that was also the beginning of the slightly-off-kilter sticker width/length on the astromech droid bodies that has sadly continued into the Mace and Vader JSF label sheets)
Most of the photos of Anakin's green JSF he takes to Mustafar are really poorly lit and the actual set prop (built full-scale) seems to differ from the CG model (just watch the Hopalong Artoo in the Droid Socket flub during the scene on Padme's veranda; as they said on Futurama: "You watched it, you can't unwatch it!"). Even the Chronicles: The Prequels book has no clear shot, CG or otherwise, of the actual Mustafar JSF, and if someone has a clear and well-lit photo of it, I'd appreciate seeing it for my own information.
