No, it's pretty clear Team Cherry doesn't give a shit about following norms. No review codes, silence while they work in peace, and "fuck you" money from Hollow Knight's success means they can do pretty much whatever they want. For that reason, I don't know if we'll get a price until release (or within a couple days of it).
Thing is, I think it will be more expensive but not significantly so. $25 to $35 is my guess, they don't really need the money but I would imagine it's a bigger and more expensive game to make now. I could even see $40, but I don't think they'll go higher. They truly don't seem greedy, they just want to live a stress free life and work on games they love creating with largely their current lifestyle.
