Hello, all. I recently ordered a new MacBook Pro 13" with Retina with 512gb of storage. When I upgraded the ram from 8gb to 16gb of RAM, the message "Ships in 2-4 business days" changed to "Ships in 3-4 weeks." What is causing the delay? Is there a shortage of parts? I also have heard that the inner design has changed, so things like the flash storage and the memory are soldered onto the logic board. Is that correct? If so, is it really going to take 3-4 weeks to just solder on more ram? Thank you. Patience is a virtue and I wish I had more of it. It has been two weeks and obviously it has not shipped yet =(.
