Well, I’m for one very keen on going down this route.
I miss Shake, loved the nodes. So I’m really looking forward for this. In fact I’ve setup an old PC (GTX580 gfx card), just to be able to learn it better.
It will fit perfectly into the workflow.
I use: FCPX for editing, Resolve for grading, Nuendo for audio, and motion/AE for animation work.
Fusion will be great for more advanced GFX work, as it has some really nice tools inside.
And I don’t really like layers and preComp…. I love behaviors in motion.
But Fusion is of another leage. Difficult, yes, but it is fun.
Remember details take time.
