I think it was a test for RD/Engineering and the market. Before they spend the big bucks in shrinking it down in the size bodies folks are used to from Fuji, they want to see that they can execute and see how many they sell.
I have no clue as to have they sold enough. It does work, perhaps the XH space will be for trying new technologies without cannibalizing the names and lines they spent several years building.
