Ari from The Tech Buyer's Guru claims he heard from someone at the MSI booth at CES 2017 that the GTX 1080 Ti will be launched around PAX East 2017:
But first a nugget of gold handed to us from a friendly rep at the MSI booth, which provides a bit more insight into what's going on over at Nvidia (info Nvidia CEO Jen-Hsun Huang apparently wasn't ready to share personally). It turns out that there really is such thing as the GTX 1080 Ti, and not only will it be available from board partners (MSI being one of the biggest), but it will be coming around PAX East 2017, which kicks off on March 10, 2017. You heard it here first, folks!As usual, we can't vouch for the accuracy of these rumors so I recommend taking this with a grain of salt. There is a lot of evidence that a GeForce GTX 1080 Ti is on the way so a launch in March makes sense.
