No laptop is perfect nor will ever be, but among all of them, we can say that Dell's XPS lineup is definitely one of the best. The XPS 15 9560 is one of the best, if not the best laptop for content creation, but Dell hopes to make it even better for 2018.
Responding to user's question on Twitter, Dell's VP General Manager of Alienware, Gaming and XPS, Frank Azor has confirmed that the new XPS 15 9570 will have a 4-lane Thunderbolt 3. This means that it won't have a bottleneck when using eGPU. He also said that the display option would be absolute best option available. The notebook will be released when Intel officially announces 8th generation H-series CPUs, which should be around CES 2018.
