Updated models with AMD graphics options expected in early 2017.
Leaked MacBook Pro Photo, No Physical Trackpad Buttons [Updated]
Engadget posts two photos of what appears to be the new MacBook Pro. The new Macbook Pro has a black bezel similar to the iMac. Also, of note is that there are no buttons on the MacBook Pro trackpad, indicating the use of a "tap" system instead.
...that "metal and glass" enclosure now houses an NVIDIA GPU, but no FireWire 400, and video-out is apparently through a connector "more compact" than MicroDVI.
There are said to be two NVIDIA GPUs inside, indicating both integrated and discrete graphics chipsets.
They have since updated and say that the MacBook and 17" MacBook Pro will not be refreshed tomorrow and that the notebook containts "two full-on NVIDIA GPUs". While no 17" MacBook Pro would not necessarily be a surprise, it's hard to believe the MacBook will not be updated tomorrow.
Update: Confirmed legitimate by AppleInsider.
