Nah. They know there's way too much resistance to direct subscription models in customers. You either need a monopoly (xblive or PSN subscriptions) or a life consuming juggernaut of a game (WoW/FFXIV). Everyone else knows they get way more custom with a subscriptionless but infinitely monetized incentivization model.

They might want to start making you pay for the anti cheat somehow, but it won't be a mandatory subscription.
