There’s nothing to say they will or will not. It’s also probably unsafe to assume that the numbers aren’t looking at least reasonable. For as many people that don’t like the price, a good number have bought the pre-purchase despite that or have pre-purchased it because they feel $50 is fair. There is also a large number of people both here and on reddit that don’t feel the price is deserved, but it’s hardly talked about in-game. Chances are their sales are not booming but they are probably not regretting the decision.
