Likely not, not in its current form. I wouldn't be surprised if in 2010 that Kinect was being sold at a significant loss (as is the usual trend in the games industry). They'd need to tweak the device quite a bit to be B2B, but given the success of game engines, asset packs, and other tools I don't think it's impossible.

Creators will absolutely pay a premium for such tech when the alternative goes for thousands of dollars (a quick google shows these devices selling on the order of 2000 to 7000+ USD). The SDK alone would generate much more value for such a product.

VR definitely killed any interest in the "core" gaming market, but I think the uses of motion tracking is a completely separate audience from VR anyway. Without some dedicated apparel, a VR kit can only track your eyes and hands. motion tracking gives you so much more data to work with, for potentially multiple subjects as well. People working with that data will easily pay themselves back with whatever they develop with it, which is why maybe a licensing deal (similar to Unity/Unreal Engine) may be a better way to monetize .
