But seriously, 3D isn't bad, I could see it happening (like how Adobe Photoshop managed to warp their editor around to allow 3D objects to be imported, that shows that any "primarily 2D" software can work with 3D), but I don't really think I'd use it at all, at least now. I'm not sure why I feel this way, though. I'd like to say it's because "I hate how 2D gets pushed away and 3D is more popular, 2D is still relevant!", but I feel that's a naive reason...
Also, AFAIK, there's a whole bunch of 2D "Event based" editors like C2, MMF...but never for 3D... Maybe that's because companies perhaps tried to make it but hit a brickwall at some point and therefore gave up? Just a thought...
