I would wait a short time to see what's happening with Wadia. Supposedly they were purchased by the same company that now owns Audio Research. Makes sense to combine the two for efficiency plus Wadia has its roots in the Audio Research area.
Certainly Audio Research is still humming along so don't see any reason yet to panic. This same and admittedly worrying situation occurred when Wadia moved from River Falls, Wisconsin to Michigan.
Once Wadia settled in their new location things seemed to workout OK but as a Wadia owner at the time the transition period was nerve wracking.
Hopefully history will repeat itself and things will settle once the move is complete.
