I'm afraid the only news is I am very busy with real life and work, my work is on the PC, so when I'm done I want to get away from it.
I'm probably going to quit GP4, I'm just tired of the limitations, this work is as low poly as it gets, and that's still too much for the engine.
There's just not enough development or scope with this game to keep me interested, I may resume after a long break, but right now I can't stand the sight of it.
Sorry to disappoint.
