As lemur pointed out, I'm not part of the DMV.
Vehicle registration info is not generally published pre-event, and so far 2012 is no exception.
I'll plus one to everything lemur said as well, the deadline hasn't even come and gone. Historically a lot of registrations come in at the last minute, though the directed ticket distribution program may have shifted that somewhat this year (as it has with theme camp registrations).
People were crying that the lottery process and subsequent ticket situation would screw over big art too, but actual results were more art grant applications than ever before, with a large number of really ambitious projects. I foresee no shortage of magnificent mutant vehicles on the playa.
Of course, weather will play a significant factor, too. In a good weather year, MV crews have an easier time of bringing their invited projects to the playa and getting them ready to pass inspection, and then keep them running throughout the week. In a harsh weather year, every step of the way is an uphill battle.
