Yeah, this is actually my plan for now. After a month, the game might probably be discounted for the first time, and combined with the 1-month premier it'll be $60. If it turns out very bad (hopefully not), there's The Division 2 waiting in March.
I wonder, what happens to the special edition goodies if we get Premier for a month then go down to the standard edition while cancelling Premier? That might be more of an Origin question than an Anthem specific question.
