I would say any estimate would be a pure guess because the devs have been really vague about scope expectations this cycle around.It's been a while, and I'm generally not that guy... but what's the ETA on this. three months?
In terms of pure render count, they'll pass 0.6 probably in January already so an update could feasibly happen then. But if they are aiming for 0.5's render count that could be 5 months away. And pure render count is not that indicative anyway because supposedly they were going to try to focus on less renders but more meaningful ones in a given scene.
So without Northpx giving indications of where we are in the 0.7 cycle any guess would be just that.
