You're not sacrificing anything. The old MBP had two usb ports and the new one has 3 available while charging. The only thing that has changed is now you can use the charging port for IO when not charging. The MacBook Escape—which history says will be the most popular new MacBook Pro by far—has only two USB-C ports and a phono jack. There are no other ports at all.
