I wouldn't mind flying one. I can't help but compare it to the CH-47F Chinook, which is already used by the US military and can carry more troops (33), lift more cargo 21,000lbs and can go 170KTS for half the price.
I don't know the range if the 47F, it can have extended fuel tanks and mid air refuel capability. I doubt it's as far as the V-22.
I think it's an interesting aircraft and is probably well suited for CSAR and maybe some other specific missions. But I just don't buy it as a replacement as an assault platform. I spent many years in an assault unit and even the Chinook was not the preferred aircraft for the mission because it was so loud and so big. It was just a bullet magnet, and fewer LZ's were available because of size.
Maybe now that the technology is out there it will eventually get cheaper, more reliable, and more effective over time but right now I see it as adding a new capability but not replacing all the other aircraft capabilities that it has replaced.
