Well a prominent alternative, as we all know, is Unity3D. If you want to be with a strong (English-speaking) community of users with regular development updates perhaps you should consider switching engines.

As for updates with 3DGS, only JCL can tell us what to expect. Aside from him, it's just idle speculation as to the progress of the engine's development. I had thought I read that Conitec was done developing Zorro and was now focusing on 3DGS development but I still see that they are updating Zorro.
