I guess the problem they encountered was that they wanted Season 2, initially, to be the finale. But they found it was to large of a story to fit into the single season schedule. So Season 2 just became set-up for the actual finale, Season 3. That's why we get alot of new things like Amy, Jessica, the second masked man, Alex's changed dynamic with the Operator, the mysterious Hotel, the return to the town, extra "unseen tapes" from the shooting of the Marble Hornets film, etc.
It's all setup for Season 3. But I do agree that Season 2 became just a little to much of a cocktease with each entry. But the eventual twist towards the end was pretty worth it, IMO.
I love that Marble Hornets struck a balance between seeming genuinely threatening (in a Goosebumps kinda' way) without breaking the suspension of disbelief by making it to out there. My Dads Tapes is entertaining, but it spoils the "found footage" atmosphere by showing people dying and this wouldn't be on Youtube if that was the case.
I would imagine Season 3 will kick off when College summer break starts, so it's just a handful of months to go!
