Not yet. The only thing for sure is early exchange node adopters will be rewarded and over time the rewards are going to exponentially increase - trading volumes simply go higher and higher the more coins an exchange adds and the longer the exchange has remained hack-free and reliable.

My one concern is if the price goes too high some people will be priced out of accumulating enough coins to run an exchange node. x5 increase from here is easy once we transition from public testing to launch.
