There will be a free binary version of Ogre Studio. Currently, there are no plans on using the GPL for Ogre Studio. And, the Core source will remain closed source. The plugins, however, may migrate to the LGPL, so that plugins can be made and distributed.. Of course, the free Ogre Studio version will likely not load unauthorized plugins, you will have to purchase a license for that (standard plugins should work just fine in the free version).
Anyway, nothing is set in stone yet
