It's still hard to deny how influential the original Modern Warfare was to online gaming. Its tight, close-quarters map design and RPG Perk System helped reign in a new dawn of online shooters. That's not even mentioning its excellent campaign, which features some of the most iconic moments in gaming. Wouldn't you want to see this in 4K?
It's a bit shocking that Infinite Warfare received an X patch but not Modern Warfare Remastered, especially since MWR was originally locked to an $80 version that had both of them. So, why not do both? MWR already supports PS4 Pro, so it'd be a mistake for it to never get an update on Xbox's newest machine.
