It's a beast
I don't know how much of the overall workstation market Apple will take with the new Mac Pro, but for film/graphics/design, this thing is a beast. For what they're throwing into it, it's actually pretty aggressively priced too (and especially so for an Apple product). A top-of-the-line system is still gonna run $10K+ once you have a professional grade 4K monitor and Thunderbolt RAID array included, but if you're actually a professional who relies on your gear for high-end work, the Mac Pro offers a more compelling value proposition than it might seem. For hobbyists and indie artists, the iMac line is still plenty capable, and PCs offer a good option now that cross-platform products such as the Adobe Suite, DaVinci Resolve and others have arguably eclipsed native Apple applications such as Final Cut. But the Mac Pro is a different kind of machine for a different customer. I expect grumbling from the Hackintosh community, but I think Apple will score with its target audiences.
