The new Surface Hub 2 rollout plan calls for Microsoft to deliver a first iteration of the Surface Hub 2 in the second calendar quarter of 2019. This will be the 50.5-inch, 4K-plus multitouch system which we saw in photos and videos in June this year. Microsoft is designating this Surface Hub 2S.
In 2020, Microsoft will update the same Surface Hub 2 hardware it introduces in 2019 with a system refresh. The garage in the back of the Surface Hub 2 device which holds the computing unit will allow users to slip in a 2X module. This module will update the Surface Hub 2 with a number of the features that Microsoft initially promised would be part of the Surface Hub 2 in 2019.
The 2S module will run the same Surface Hub system software (an iteration of Windows 10 Enterprise that's known as "Windows 10 Team") as the current Surface Hub 1 does. Officials declined to say whether the 2X module will run the long-rumored Windows Core OS and "Aruba" Surface Hub shell as part of Windows 10.
Microsoft officials deny there's been a delay in delivering the Surface Hub 2. Instead, they say that they are listening to customer feedback, and customers wanted to continue to have access to the original Surface Hub 1 experience. Microsoft is believed to have had trouble meeting demand for Surface Hub 1, so this staggered release also may give the company a way to keep shipping Surface Hubs to customers who are continuing to order them.
