I will say this, at face value, I am against cloud streaming exclusive games.
The only way this would be of interest to me, is if games get made that require a lot more GPU power/performance than what a Scarlett console can do. If say a XGS game or 3rd party game needs to use several instances of Scarlett SoCs in order for someone's vision of a game to be realized.
I mean the same sort of thing that Google showed using multiple Stadia GPU instances/server blades.
Games that could not even be done on a single high-end PC.
That might be enticing but I would expect that to happen for years.
Other than maybe that, I don't think anyone wants to see cloud exclusive games.
