The use of DP1.1 is what is keeping us from running more than one monitor at this point (per DP plug). Notice how only the 27" iMac can run two additional monitors, because it has two ports. What I think people may not realize is that per Thunderbolt controller you can only have two mDPs. So if Apple wanted to enable the 6 monitor eyefinity support for the top end GPU they would have to include 3 Thunderbolt controllers (
per Intels graphic) because they don't support more than 2 DP connections per controller.
So, if Apple would have been smart enough they would have replaced todays ports (ether, fw, TB, 3 x usb) with dp1.2 and 4 TB+usb3 ports. Ether + fw could be handled with dongles to TB and this would have given future upgrade possibility to 10G ethernet. On the motherboard fw controller would have been replaced with another TB controller.
As a result, there would be one port less than now and only two types, so if Apple's long term goal is to make less ports simplier, this would be it.
If they would choose to keep the amount of ports the same, they could even add µHDMI to the mix for user convenience.
Maybe stand-alone dp port could utilize discrete GPU and TB ports integral GPU.
You could attach that über-geek hyper display with 20Gbit/s bandwidth after a decade from now or you could attach 8(!) screens to your new mbp today!
Otherwise you could also daisy chain 24 TB devices to one mbp!
And you could have a dock connector for all these ports and devices, that you could undock in one click and leave that room full of hardware behind when heading home from work.
But no, someone said that we need shine curves and reflecting screens and fingerprints and internal batteries and facetimeHD more than that...
TB in it's present state is almost as big joke as not including usb3 to "the most advanced computer on the planet"!
