Ummm this isn't exactly news. The last season (and only season) of rescue me to come out on bluray was season 3 and that was a few years back now. Season 4 didn't come out on blu a few years ago, and now season 5 won't thats old news.
As for me I refuse to buy stuff on dvd if I know it was shot on film or in HD. I don't want to get double dipped.
The fact they used rescue me as an example makes me think this article isn't very factual, as the decision to stop putting rescue me on blu was a very old decision. Hopefully we see more release on blu in the near future (as more people get the players, and those of making blurays goes down).
