That’s fine if it’s a new product or product category (I’m sure they will preview their AR/VR devices long before they ship), but when it’s something that replaces an existing product in their line it’s a horrible idea.I think they should do what EV makers are doing and preview products a year or longer before they begin shipping.
If they specifically detailed these new MBPs a year ago they would’ve sold very, very few four-port 13” and 16” MacBook Pros over that period. Letting people know what’s coming kills the desire for what’s available now.
