I never bought TNG on DVD, and I'm glad I didn't. I will be buying every season on bluray, no questions asked.
It's just a matter of being able to find this apparently "fringe interest" title in stores. (Not that I consider it fringe, but it seems the retailers who don't get adequate stock do.)
Is there going to be a standalone release like there was with 3 (BoBW) and 4 (Redemption)?
