I get the sense that they are planning to include dice tricks in 5E, which gives me the further hunch that the OGL is not going to be in use. And honestly, I don't expect even a revised GSL to be useful to more than a few publishers who want to write in very limited areas of support. I figured at some point they would introduce some element(s) that would suggest which way they would go regarding the "open" licensing. This feels like it to me. We'll see.
Why a "dice trick system" can't be open?
