When devs say "We cut out x feature to better support x feature" it pretty much never happens and is almost always PR spin covering for a fucked up development cycle. COD BO4 did the exact same thing, it cut the campaign and fanboys were screaming from the rooftops how much better the multiplayer would be because of it. Well when the game released it was clusterfuck, probably one of the most hated CODs ever, and pretty much just a platform for selling microtransactions and little else.
And then afterwards a report came out saying it was going to have a campaign, but got scrapped due to how much of a mess its development was. Would not be surprised at all if the same thing happened here.
