Arrow not releasing this movie on DVD

[UK Wolfman]

I've just gone on to Amazon and looked up Bird with the Crystal Plumage, and apparently, Arrow are refusing to release this movie on DVD, and will only be bringing out a Blu-Ray release. I don't own a Blu-Ray player, as they're not currently region-free, and I'm obviously not the only person who doesn't own one, as there was a somewhat ticked-off review on Amazon that stated many of the things I've just written. DVD is not a dead format yet, and Arrow appear to be releasing. or have already released, most of their other films on bothe formats, so why are they not doing so with what will surely be one of their best selling titles?
