You're probably wanting a game development update that actually tells you what's currently up. Well, the reason why progress is so slow is because we haven't made any. I can't tell you much, because my brain implodes just having it explained to me, but to sum it up in a TL;DR... Shaders are evil. (Game devs should know exactly what I mean...)
We're going to figure it out. Or, rather, my coder's going to figure it out, and I'm going to throw tutorials at him to help, because I tried to learn to code shaders, once, and my mind went BSOD from a two second glance.
