I have not seen any sort of rumors about ATI getting back into the pre-pro biddness in a long long time. Though there are lots of older ATI units still driving moderately complex residential & commercial installation -- when those fail who knows what the custom integrators will need to do... The speed with which firms went from "upstart" to "market leader" to "flame out" was a function of a whole lot of craziness in the residential real estate market and the pace of technology change. With the sorts of turmoil that still is the norm in China I would not be betting on anything.
