Good to see it's marked as the Collector's Edition - there are 1-disc and 2-disc DVDs coming out, and the press releases I've seen were fairly vague on whether all the special features would be included on the HD versions.
The Host is a treat. Black Tiger is probably much more of an acquired taste, but all that's required to enjoy The Host is a love of monster movies and a tolerance for subtitles.
Probably BD as well, given how format-agnostic Cuban's companies are in general. Cool to see Magnolia putting things that are a little off the beaten path on the HD formats. Hopefully they'll also do this for Tears of the Black Tiger, whose visuals scream for it.
