Yeah, because The Funhouse and Obsession are in the same league as Evil Dead regarding home video sales
When ABUK first started putting DVD's out it was a very different world than it is now! Yeah, there was a few VHS collectorsd/obsessives, but nothing compared to the disc freaks you get nowadays! Evil Dead is a massive cash cow for Renaissance now, comic books, video games, DVD's, all that shit, so if they're going to re-release (and I fully expect they will, just like in the US - hence that ones region locking) it will be a major release to rake in those collector monies, not a limited Arrow Video one.
AV can't even sell 500 copies of the "revered" ZFE that everybody was supposedly dying for a slipcase version of, so the brand can't be that strong.
And I think you misunderstood my "taking the piss" comment, it just means "you're having a laugh" out here in the flat lands.
