Apparently Sony has quietly announced a wireless TTL lighting control system complete with MIS receivers to attach other lights to. It'll be able to sync up to 1/250th of a second and provide HSS as well. Looks like it may be decent if it works with other non-Sony products. It would be nice if they were able to control and adjust other Studio lighting from popular brands like Profoto, Elinchrom, Bron, Hensel, Bowens, etc.
