Guy in Holland posted on blu-ray.com that he got Barbarian & Destroyer yesterday in store, it releases July 6. He said its by Fox, so it should be the same disc as the Fox UK release, just different cover with Dutch age advisory & text. He said he has a region B PS3 so he can't tell if it's region free. He gives it pretty high marks saying "Barbarian is pretty grainy but I believe very faithful to the source material. It looks very good but obviously not the best disc ever made. It could have been better but its miles better than that grungy dvd I have, and thats pretty much all I wanted".
I went ahead and included in pre-order for the UK release in an order from Amazon UK. If it's region B locked that's not a problem for me, and it's a bit cheaper than Amazon.com's price for the Universal release and I'll have a week or 2 earlier. I also have a deep mistrust of Universal catalog releases as they far too often apply the magic DNR grain & noise removal along with a healthy dose of EE.
EDIT: He's now posted pics of the back cover & discs, and they're marked Regions ABC so it looks like it's region free. DTS-HD Master Audio 5.1 & French 2.0 DD, Dutch, French & English subtitles.
