Can anyone summarise the services that will remain with Howard Snaith?

I have seen (today, Wednesday 15th) a small (midi) coach in Snaith livery heading out of Hexham with an 880 sign in the windscreen at 18:15 or thereabouts.
I understand that GNE will take over the 880 (via PCL) between Bellingham and Kielder (not serving Hexham except by connecting service 680 from 3rd August.
My sightings of the Snaith coach doesn't seem to fit in with any existing timetable.

Have all of Snaith's PSV contracts been removed? (along with school contracts?)

If so, will HS survive on private hire alone?
