I don't see why they wouldn't look at the numbers on it. But it depends on if the sales hold up, whatever they've been.
I guess it would be many years down the line. From what I've read I believe they could release ENT on Blu-ray much more easily than any of the other shows as it was shot in HD anyway but I'm not sure why they haven't.
