If Microsoft undercuts the PS5 price, it'll be a coup. Right now it's all about hype and jostling for position. I believe both prices have been fixed, only neither Sony nor Microsoft are going to announce yet. Whoever announces second gets the last word. Microsoft wants Sony to announce first so they can come in and do what Sony did in '95. Sony wants Microsoft to announce first so they can come in and say "Yeah, we're $xxx more, but this is what you get for your extra money!"
