It also looks like Maxon finally gave in and decided that the best way forward in shader construction is to make it node-based.
On CGsociety, Maxon also dropped the hint that the Motion Graph could become node-based too, but users would likely have to wait till next year at the earliest.
For other uses, the video has no hints about improving things that C4D has been falling behind in (such as texture painting and character animation). They’re basically playing it safe and focusing on a few core areas again (with the exception of the viewport optimizations).
