Wow. They wanted to ship 15 million through March. That is nuts. Even if they get 11 million out there that should be plenty, they'll still probably have a couple million sitting around at that point. 15 million would probably get them into next Fall.
Even more absurd of a plan given it was reported that Sony freaked out over the pricing of Xbox and apparently had to slash their planned price of PS5 because Xbox came in at a lower price than they had thought.
At least at 11 million through March there should be plenty of supply for everyone to get one with plenty left on store shelves.
