Well! Keep in mind this is just fan hearsay. Second-hand source, so I wouldn't count it out just yet.
But keep in mind, also, that it fits what we already know, and thedrumanimal doesn't really have any reason to lie. If the DVD were to be released at the very tail end of May, we'd be expecting news... well, now! Six weeks is about right for the promo period. So, yes, it seems very likely.
Funnily, the gap from the gig to the DVD is now longer than the gap from the drummer auditions to the drummer doc - and to think how much we complained about that! More complicated end product, I suppose, so, again, unsurprising. Shame, but it'll be done when it's done.
