No matter the reason, GM and Chrysler are now confirming that they have pulled out of October's Tokyo Motor Show, and word is that Ford didn't meet last year's sign-up deadline, so they probably won't be in attendance, either. Given the high cost associated with building and staffing an international auto show stand - not to mention diminishing crowds and increased exposure through other forms of media (*ahem*) - this sort of story is likely to become more and more common until industry and the wider economy sorts itself out. In fact, if recent reports are accurate, the entire Tokyo Motor Show is itself in doubt.
