Well we would need a report about their 1st party studios as well.
It could be that they want to strenghten their own studios as much as possible by giving them the dev kits much sooner.
True, but their adquisitions have been relatively recent, so they might not have anything major ready for launch. It seems like Scarlett is in a rather awful situation right now: if it releases early, it won't have the software needed to push back against PS5 and the PS4's momentum. If it releases later, the PS5 will probably have a decent inertia that will be difficult to stop. And in both cases they have to supply both the Scarlett and the X-Cloud the resources needed to function, with the potential of also splitting up the userbase.
You know it deserves the GOTY.
