I'm shaking my 8 Ball and I'm seeing something in that little window...

Apple may talk about a new product that either helps with collaborative workflow and/or audio (Logic Pro X))
No hardware announcement but they'll be a very strong hint.
Note that Adobe has mentioned multiple GPU use for PPro.
As part of Apple's FCPX roadmap talk they'll mention that FCPX will support multiple GPUs as well. Of course you know what that means. Their roadmap talk could either be for "this year" or "this summer" which may be a clue on when the MacPro happens for that multiple GPU support.

Still getting green frames with the new update! I guess they haven't fixed it for multi cam clips that have Magic Bullet Mojo applied.

This is exacerbated by editors who stubbornly dabble without training and pronounce FCPX an abysmal failure as a "Pro App" and they have the scars to "prove it."
