They're expecting an order in soon, but don't know what's in / on it yet. I know some barrels are coming, waiting to hear back on my 6.5 and 260 barrels. 6.8 don't appear to be that common, barrels but not type 2 bolts, you may have to special order.
Standard rifles are not coming with a type 3 gas block that I know of, maybe thats changed, but for competition rifles it will be.
