I have a feeling the MacPro, the old 13" and 15" MBP and iMac are all EOL.
It's pretty clear where Apple is going. The desktop, as a standalone device, is over. The margins are horrible, the sales decline quarter over quarter. With an HDMI port on the new MBP, it's pretty clear an Apple-branded TV/LFD is in the future.
I wouldn't be surprised at all if Apple debuts a 4K display in January '13.
