As FreeSync is based off Adaptive Sync (an industry standard), it will eventually make it way into inexpensive monitors as well. It simply requires an updated scaler, so the cost difference to make a monitor AS compliant is negligible.Since this is mostly a gaming technology on expensive monitors, Intel isn't even a player.
Laptops and low end computer systems will benefit from Adaptive Sync more than high end systems. They will be the ones most likely to be running below 60 FPS and will thus be the most susceptible to tearing. Also, AS has power saving properties for static desktop content and low framerate videos. Both of which would appeal to corporations and laptop manufacturers, which are Intel's bread and butter.
So I would be highly surprised if Intel does not jump on the Adaptive-Sync bandwagon as well.
