I guess not a major surprise. All 3 contenders (V-22, C-2 re-do and Viking re-do) all had pros and cons. The Osprey lobby seems pretty well connected, and the F-35 enigine now looks like it will fit with a new container solution.
I see being able to land on each ship in a battle group, over the spoke and hub of C-2/helos, as being a definite plus. Speed is likely not that much off from the C-2. Range and cost may be...
