NVIDIA prepping 2-in-1 Shield with 13.5-inch screen?

An update to the NVIDIA Shield Experience software contains references to a new device that's codenamed "mystique". XDA Developers writes the device seems to support three UI modes: Dynamic, Tablet, and Desktop. Some extra digging suggests this Tegra-based product may be a 2-in-1 Shield tablet, with a 13.5" Panasonic display with a 3000 x 2000 pixels resolution.

At least for now, it's unknown when or if we can expect the launch of this device. Not that long ago, NVIDIA CEO Jen-Hsun Huang said NVIDIA is not interested in launching new Shield products, unless it can offer a product that offers more than just a "minor improvement" versus products that are already on the market.

It may seem strange for NVIDIA to re-enter the market with a new mobile product given that they canceled their SHIELD Tablet K1 successor in 2016 citing unspecified “business reasons.” The release of the Nintendo Switch likely played a big part in the cancellation of NVIDIA’s 2016 tablet, though we don’t know. We reached out to NVIDIA to see if the company would like to comment on a summary of our findings regarding the NVIDIA Desktop Experience feature and “mystique.” A spokesperson for NVIDIA declined to comment, though they referred me to a previous statement I was given as well as comments made publicly by NVIDIA’s CEO Jensen Huang at CES 2019. For reference, here’s the statement I was given when I previously wrote about the existence of a new SHIELD remote and SHIELD controller:

It’s fairly standard practice for various concept codenames to appear in codebases. Those references remain even when it becomes unlikely that the concept ever goes into production. We can’t comment on which codenames refer to product concepts that are active vs which ones are inactive, as it can be fluid. However, I can confirm that none of the codenames below refer to products that have launched publicly.
