This should be good news for you! There's a R2 version of the Chanthology coming out. Check you local e-tailer, but the site I linked to is showing it coming out November 1st for 23 pounds. Interesting enough, that version is 3 discs because they're using double feature discs.
By the way, are you familiar at all with a British company called Orbit Media? They have released Charlie Chan in London on DVD (the first of a proposed series). Unfortunately I've heard some less than flattering things about the general quality of their product from a couple of people.
