I guess the naming has always been an issue for MS. The actual brand name is just the placeholder they never replaced. Would they be better off with a rebrand entirely? Something that they can rebrand all their services, so instead of being XBox Game Pass, which associates the service on devices with the console in a mildly confusing fashion ("I own a PS4 so aren't going to look at XBox thing on my phone."), turn everything into...Azure, or some other shade of blue, and have Azure Game Pass and AzureBox or Azure Game Centre.
Is the XBox brand strong enough to be a positive, or would it be better served being replaced? In the home market, it's probably worth keeping, but if MS want to reach further, maybe it's time to hang up the association with 'the box to run DirectX' and pick something more purposefully named?
