I think a lot of the controversy regarding the IVT has to do with the word "development". I can't suppy any specific references off the top of my head but I think we were led to believe that the IVT was much, much further along the development curve than is apparently the case. It looks like we are past the Engineering Model phase and somewhere in the P (prototype) 1 phase. This would imply to me that we are about 18 mos. from the B (build authorization) 1 phase. When you add to this the uncertainty over the fuel savings and no information re costs the near term outlook isn't that good. Long term, the competition will not be sitting still. I haven't tracked down a copy of the RBJ yet but if I were a potential buyer with my own job and reputation on the line the only way I'd deal with this group is to buy something outright after doing at least some testing of my own and then get this group out of the loop immediately.
