Sorry I've been away from the boards over the last month, but I have had quite a bit going on!
I share your frustrations regarding Sony's inconsistencies in handling the Stooges. The last time I heard from the contact I have there (in the PR department), volume 2 was, indeed, "on the table." Sony must be happy with the sales of volume 1, even though I could NOT get actual sales figures from them. It is still selling well on Amazon.
I'm sure we will see a second volume, but how long Sony will wait to release it (and subsequent sets) remains to be seen.
I have forwarded all responses that those of you left to Sony. All we can do now, sadly, is wait. Our boys and their fans deserve better treatment. I have no idea what makes the powers that be at Sony HQ do what they do. It sure doesn't seem to make much sense from my viewpoint.
As soon as I hear from my contact and get the official press release, I will post it here ASAP! I can only hope they are preparing the restoration process for this 2nd set as of this writing and make the announcement official in the next month or two.
