The most poignant example I have comes from gaming, but I think it illustrates the point. In Elite: Dangerous, some of your menus are to the left and right of your avatar. Normally, you'd have to press buttons to focus the camera on these menus; in VR all I have to do is look at where that menu is and it pops right up for me to use.
It actually made the interface _way_ more intuitive, easier to use, and significantly faster because it played on my expectation of the result. If something similar could be designed on top of Bloomberg data, I think you'd see finance people trampling each other to get it.
This would be particularly true if you played into their existing behaviors and motions; they wouldn't have to learn anything, it would "Just Work".
Same reason I won't buy the new Macbook pro - they fucked with the ESC key, they instantly stopped existing as a viable product for me.
At no point did I suggest messing with their keyboard - just give them better visualization possibilities.
Any change, no matter how much it improves the workflow or UI is met with bitter resistance, because the users do everything from muscle memory, and small changes break that and slow them down.
