Hm, judging by the activity in this thread for the last month my bet is on PMP being dead before going live on an exchange.
The only way PMP would be "dead" is if I and the rest of the team stopped working on the project.
I've got more support now and we are working on some pretty interesting features so I wouldn't count on us giving up when we've only just started.
We've got a unique staking4tx system planned out and a simple anonymous send feature in the works.
As well there are some more services (gambling sites) on their way. Everyone likes gambling right?
