I'd also like to see MASH on Blu-ray, and Andy as well. I think they did season one for that and stopped. There are so many really.
It's difficult sometimes because you want to grab something before it goes out of print, but you don't want to have to buy it twice. Once on dvd and then on Blu-ray. But what if it doesn't come out on Blu-ray and then the dvd's are gone too? Now you're screwed because you waited.
That's how I found out about the movie finally coming to Blu-ray, I was looking for the dvd because I figured it wasn't ever going to get a more modern release.
