Make of that what you will, but it’s quite funny to once again see rumours emanating from source A, then being cited by B and then A using B’s citation of their original rumour as validation. So let’s cut through the chaff. There are basically three main points here that everyone is regurgitating: USB 3 NVIDIA GPU Retina Display USB 3 – confirmed via plist reportedly in the ML code. Without seeing the snippet personally, it’s impossible to confirm, but this is a fairly logical one. I think we can be fairly confident of this happening. NVIDIA GPU – again, just like the above it’s difficult to confirm that the code being cited exists without seeing it personally. Considering the work NVIDIA has been doing in terms of drivers for OSX that you can download and use with a Mac Pro (http://forums.macrumors.com/showthread.php?t=1360927), then this could well be a reality since they wouldn’t be writing drivers for xxxxs and giggles. Retina Display – The high resolution icons in ML do suggest that this will happen sometime in the future. However, don’t forget that high resolution icons were already found last year when Lion was released to devs. I think this is the least likely to happen out of the 3 main points, but may be a possibility. The sub-points are: Firewire ports? Ethernet ports? The rumours around the ports being gone are based on this paragraph Considering Apple's penchant for (what they think is) simplicity, the reduction of ports could happen. We can all argue that these ports are important or not. There are adaptors out there and more are coming. Sure, adaptors may not be as handy to use as having the port, but it is what it is. Looking at NAB 2012, the professional video and audio device manufacturers are embracing Thunderbolt with both hands. TB is also coming to the PC. Whatever we get in the latest refresh there will be interesting and exciting times ahead with joy, trepidation, gnashing of teeth and, of course, the mandatory "is my computer running too hot?" threads.
