For example "Tonal" is a work out machine that attaches to the wall, with a large video screen (probably larger in the next generation version).

Regarding your wall projector, it would be cool to have a camera project your image onto the instructors. Then some computer vision magic to grade how close you matched their exercise.
Just because a company offers a product that does something new and different does not equate to where the industry is truly going (as much as founders/CEOs may wish otherwise).
It's more about where the customer/consumers are going...yes you can lead them to an extent, but on that note are products like Tonal actually selling and if so, what clip and density?
I would ask for evidence of adoption of something (beyond just the mere fact it exists) to support the "where the market is going" type of thinking...
