Nothing official, but according to Darrell Rooney, co-author of this year's HARLOW IN HOLLYWOOD book:
"Word has it that the much awaited Jean Harlow dvd box set will be released on the last Tuesday in October: the 25th! No announcement coming till the day of the release."
What's on it? Per Rooney, "Everything not on dvd so far except for 'Red Dust' and Hold Your Man'. Maybe those are being held back for another Gable box set release."
That would mean it would include solo Healy efforts BOMBSHELL (1933) and RECKLESS (1935).
Rooney posted all this on Facebook. Not sure if it's a pressed set or a burn on demand deal (sadly, odds strongly favor the latter).
