Gox was always a poorly designed exchange but like bitcoin, it was the first so reaps the rewards, i doubt it will die as much as everyone wants it too.

As for incryptex, they haven't even mentioned doing USD purchases so far that i've seen anyway, that would mean they have to be a proper company and register with FinCen or they'll have the same problems as Gox does with withdrawing funds.  Why do you think Crypsy doesn't do USD stuff yet?  I'm sure they are having problems with FinCen as well, and I believe the guy who runs Cryptsy has a legal background too.  The people running incryptex are going to have to put a pretty decent investment down for the hardware or renting for that site because they've picked some high volume coins to trade on launch, pretty much the worst ones, all the popular ones.  Doge coin alone will stress that exchange on its own.  Remember the lag on exchanges like Cryptsy when Doge hits peak volume?
