HTC will have a new product event on January 12th

This second generation HTC Vive could be considered as a mid-generation refresh for SteamVR, likely containing several ergonomic improvements and have the same display resolutions, refresh rates and field of view as existing HTC Vive headsets.  Upgrades to display components, such as higher screen resolutions and refresh rates, will result in higher PC system requirements, limiting the headsets potential userbase. This makes it likely that any changes to the HTC Vive will be to reduce the headset's cost and improve the headset's usability rather than making any major hardware upgrades. 

Back in September, Valve started recommending that SteamVR headsets use Triad Semiconductor's new TS3633 integrated circuit, which Valve has helped Triad to develop. This new circuit not only reduces the component count for the HTC Vive's tracking system but reduces the headset's power consumption, mass and improves the accuracy of their tracking system. 

In total when applied to both the HTC Vive headset itself and its motion controls this improved tracking system removes a total of 2560 component placements on the HTC Vive, making the headset easier to produce and much more reliable. Below is a detailed explanation from Triad's VP of marketing and sales, Reid Wender, on how this reduction in the component count will benefit the HTC Vive 2.0.
