I miss, DarknetGuy says all the ports on the MBP will be capable to deliver video upto 5K on TB3 upto 4K on USB-C only you can charge the Mac from any port.
DarknetGuy has no info on Thunderbolt display with integrated GPU, don't discard but only sure about std Thunderbolt 5K retina display, also has no info on TouchID integrated, but maybe part of the Magic Bar.
DarknetGuy is the nick I gave to some leaker that post at some .Onion site dedicated to trade insider info, her purpose is to gain reputation until offering bounty-paid exclusive leaks.
he/she 100% is confident about the new MBP to be launched at WWDC, but availability due AMD and other supply chain delays is expected for august.
PD. before you ask I deleted that .onion address on every computer, burned storage and dropped my pcs into an active volcano.
Nice plot twist at the end there, mate
