Using a Raspberry Pi would be like a dongle... I'd like to get my hands on one to play, currently, there is a 12 week delivery time on those as well and you most likely would want it in some sort of case for it as well.
While most likely a solution, not a real clean one for mass marketing. That will come though.

Hopefully it does include support, but that is still a bit pricey and also not very portable.
Think of something you put in your briefcase, take out for a meeting, plug into the HDMI port of whatever display is in the room and play. So it needs to be portable, reasonably priced and easy to use out of the box without a lot of fiddling with it.
