That is something I really don't want: a third reboot ...
Considering where Hollywood is headed, you'll probably get it.
I mean, with JJ gone for Star Wars, even if they squeeze out one more film, I see that being the end of the line for this continuity, after which they will probably think "We did fine, but there was too much collateral damage by trying to split the difference. We should just try a full reboot next time."
It would be kind of like the reboot of Spiderman and the pending reboot of Superman, without a long gap between. The audience has become accustomed to this sort of reboot cycle.
All it will take is finding a director/producer with enough of a strong critical reputation in Hollywood that will give people a sense that it will be worth their while to lather, rinse, and repeat, like when Chris Nolan finally teamed up with Zach Snider on Man of Steel after Superman was in development-hell for many years. Having Nolan on board automatically gave the effort credibility.
