One of the real problems with LTA/hybrid - and HAV themselves walked into it with the LEM-V go-around - is that for some reason, everyone forgets that every such aircraft that isn't a repro-Goodyear or smaller is a new type of flying vehicle. I think HAV is showing more sense this time and treating the first AirLander as a demonstrator of what could be done, rather than promising to go fight a war in three years from program start.
