Xbox is just going to be a brand/publisher I reckon.

There’ll be ‘Xbox verified’ console PCs or somesuch that aren’t necessarily made by Microsoft, and there’ll be the Xbox app for games and streaming, and Xbox published games.

And then another 5-10 years later they’ll phase that out and just be ‘Microsoft Gaming’ or somesuch branded, and the last traces of Xbox will be gone.

D4 also had a DLC recently. Yes the D2 update was just now so its spike is newer but it’s not meaningless that D2 has surpassed D4.
