The Infinity Ward Twitter account teased this today. I assume this is a reimagining of the game to follow-up as a sequel to Modern Warfare (2019).

Supposedly launches under the radar tomorrow, going by a PlayStation Store listing. A trailer has leaked. Fully expecting it to be a microtransaction delivery system like the first remastered game.
