The Surface Book was announced back in October 2015 so it would be time for second generation of the device. While there have been rumors that Microsoft would launch the Surface Book 2 next month, this now may have changed. According to a new report from ZDNet, Microsoft might not start shipping a new Surface Book until early 2018.
This October, we probably will only see the launch of a Surface Pro with LTE. At the moment, we do not know a lot about the next Surface Book but it seems like the next year will be a very interesting one for Surface fans with a new Surface Book and a new Surface Hub. Furthermore, we also might see the rumored Surface Phone.
