It is a separate cost David. I asked them the same questions a few days ago and they wrote this back to me.

Hi Liz,

Any existing Pro Plus purchases will remain completely unaffected by the launch of Genesis Pro. Existing Pro Plus customers will still continue to benefit from theme support should they need it and new StudioPress theme releases, just as before. But they will not get Genesis Pro for free. The key takeaway is that Pro Plus will simply be unavailable for purchase after June 10th, with Genesis Pro taking its place.

Let me know if you have any other questions.

Cheers,
Robert
