Well, they did a significant upgrade to Final Cut X, so that's a good sign. It really looks like a professional app now, and does a lot of the stuff I wish it did from the beginning. That, and the fact that Logic is still going strong, are good signs.
I think it comes down to this: if Apple's intention was to wait until there was an AMD GPU worth using in their nMP chassis, then there's a clear marker for when a Mac Pro would show up: once Vega is ready. I doubt they're waiting for Skylake Xeon because Xpoint 3D seems to be a total mess (and is being delayed until Kaby Lake apparently.) AMD's GPUs were way too hot and power hungry last generation, they've righted the ship to an extent. If Vega becomes available, and nothing's changed, then it's a pretty good sign that they're not interested anymore.
This all being said, the real reason I want a new Mac Pro is so I can stick the equivalent GPU in my Hackintosh.... Can't afford Xeons as a student, but I'm not interested in paying for a laptop attached to a 5K screen. A non-Xeon desktop shouldn't be such a gaping hole in their lineup.
