I suspect at this point there is just nothing else to tell. Just because we desperately want a happy ending doesn't mean there will ever be one.
As far as Melissa Bianco, Matt Miller, etc., people that high up on the food chain are going to have trouble finding comparable jobs somewhere else. They were working on CoH for over/just under a decade. Even Matt said people usually get promoted into his job, not hired from outside to do it.
Kickstarter funding doesn't just go up with the snap of your fingers, and PS got totally blindsided besides. I would imagine that most of their time was initially spent trying to save their baby, and only when that fell through for the final time (with NC's newest "NO WAY JOSE' SO SHUT UP NOW ONCE AND FOR ALL, PEEPS" announcement) would they even begin to think about licensing/building a new engine, and perhaps starting a new game.
I really wouldn't expect to hear anything until next year sometime about any sort of potential new game, if anything is able to happen at all. And much as I admire the heartfelt attempts at Titan City by the player base, I seriously doubt someone like Matt or Melissa is going to get involved in something where they can't even hire or control those working on it. I wouldn't hold your breath waiting for that one.
