Well, first of all, we do love our DJS-1000 users, and the reason there's no dedicated forum for it is the same reason there's no dedicated AS-1 forum; they're part of the same product family.
Besides, the forum staff consists of myself plus two other moderators. I do all the work to get this thing organized and running. I'm in the midst of a redesign for the site and have already taken this request into consideration for the product groupings, but it won't be something that is launched for a few months yet. So until that time, please continue to post here and we'll be happy to answer your questions.
As for rumours, we don't allow rumour-talk on the forums because Pioneer DJ is ALWAYS working on "the next" whatever, although even I would be surprised if there was a launch of a SP-16 MK2 so soon.
And yes, the firmware update is still coming!
