Dude Alex, man, come on...
But in all seriousness, I doubt it'll happen due to a few reasons: one of which is baby Roman H. D.
The other reason, which is perhaps an argument for why it shouldn't, is part of what Alex mentioned in the first post. When it happened the past two times, it started very much as a small forum thing. Other intense tMG fans went and were able to go, but it was announced here, and here first, before (at least the second time) making it to the front page later. But plenty less people check the front page, even, than follow JD on twitter. The size concern would be entirely unmanageable that way. Think, for example, how quickly the 500 All Survivor's Pack stuff went from Merge, and then keep in mind that maybe
maybe 200 people get to go to Zoop. It would be a madhouse if it were first come first serve. It it does happen, it won't happen that way.
Which leaves the only other option left, as I see it, for Zoop III happening: some sort of lottery system. You enter, and if you're lucky, you get to go. It's not out of the question, but I feel like the community (ie, the people around here) are very likely to get largely and vocally grumpy about the system if we didn't luck out (including myself, just so it's clear) which is unpleasant, sure, but also unpleasant in JD's space. More importantly, I feel like that kind of thing might ultimately taint the memory of what was a very cool and awesome thing. It's not the only cool and awesome tMG thing to not really be feasible anymore, just another one to add to the list.
But despite my thoughts that it won't happen, if it gets announced I'll do my damnedest to get on board again, of course. That weekend of Zoop II was more fun than it had any right to be, really.
