Wasnt the whole thing supposed to be a big update to 2022 title? I remember reading there was going to be no new title for this year and instead MW2 would get a big update.
I bet they saw how dumb people are who are willing to buy a premium version of a battlepass every season on top of all the crazy skins they push out. So, instead we get a "new" title which literally plays and feels like a DLC for MW2 which it was meant to be.
