Considering WB more than likely has spent MILLIONS of $$ hopefully getting clearances, licensing music and actor appearances, and paying off Fox in some fashion to get the home video rights, I suspect they will pull out all the stops and light it up with all kinds of various editions, with some editions catering to the casual fan and other versions catering to the die-hard super-collector who's waited a decade or more, all in order to maximize their return on their rather substantial investment for years to come.
I'd certainly like to know how many suitcases full of cash WB/DC had to throw at Fox to get the distribution rights to this show. Considering how much time, money and effort that went into getting the show, one would thing a full HD remastering of the show would have no issue whatsoever getting financed.
But who knows? I don't think WB ever released an HD version of a pre-digital classic TV series. Will they stick to their guns or go whole hog remastering in HD?
Also, to address prior comments in the thread. I don't think anyone is saying "Blu ray or no sale".
I wouldn't be surprised at all considering how rabid parts of the Batman fanbase can be.
Personally I wouldn't really mind if it wasn't. It's not like it was ever intended to be viewed at that definition and would make an already cheesy show look even cheesier. Which is a good thing or a bad thing depending on your POV
