I think this is a good move. The A7 Extra version has no shaders which are important, and Unity Indie has no shadows which are also important. So its a sort of tie, both Unity Indie and A7 Extra are not able to create realistic scenery, you have to upgrade to the not free version for a professional game.

This step is $199 for Gamestudio and much more for Unity, so it looks as if Gamestudio Commercial is well placed against Unity. They only now need to give WED and MED a more polished look .
