Exactly. I see this as a growth industry. What's happening now with TOS-R is experimentation, one episode at a time.
Also who is to say CBS will do all the series? TNG is arguably Trek's most successful franchise. As much as we here like DS9, the general public, who has to embrace remastering for it to be financially successful, has never warmed to Sisko and company. It might well never receive HDTV treatment. It just depends on how much it would cost versus how much money CBS can make on the project.
