Now they want to sell the propietary version on Linux, but nobody cares about it.
Obviously they are desesperate to attract market, but they are failing.
There will be source code. I looks like it will be more open core though.
As for nobody caring, this is one of the most watched and wanted ports to Linux. The first actually useful professional video editor. Something Linux does not have. All the open source ones are shit. They are fine for simple things, but not for any complex pro stuff. Only kdenlive comes even close.
