I would start by talking about what is great about Diversion -- what it lets you do that you couldn't before.
Since you mention gaming and perforce I looked in vain to see if it supports binaries (a major limitation of git -- just simply not in its design space). "Binaries" can actually mean for some people compiled code -- not for me but I understand why people do it -- as well as images, data files, Word files etc.
Sounds like the second is scaling but you don't say what you mean by that. Git scales pretty well until either the repo & its history gets enormous or when there are a lot of people making simultaneous changes.
The realtime collab integrated with a version control mentality could be interesting -- a major problem with google docs is the lack of useful version control (even Word is better).
And why cloud native?
Once you've done that you need only briefly mention "why not just use git instead?"
