Good Q.
No, we will not expire Pro in any way.
In fact, the new mediaADNET V2 coming in Feb is built on top of Pro.
But, we will continue a parallel effort to make Lite less... well lite.. and more powerful, but always keeping it simple to use and open source. Pro will always have more advanced features... but it's true that it's not a 100% in sync effort as lite for example has a more robust implementation of the Location based component and setup with FasterQ...
hope this help...
