Nvidia may not be keeping its latest Shield gaming hardware chained to a set-top box. According to some Bluetooth certification documents uncovered by Chinese Android site Juggly and similar Wi-Fi Alliance documentation discovered by Liliputing, Nvidia may be updating its Shield handheld with the company's latest Tegra X1 SoC.
The speculation is based on the fact that the Bluetooth SIG documents describe a "system mainboard" for both the Shield set-top box and the as-yet-unnanounced Shield portable. The Wi-Fi Alliance's product listings also speak to the existence of this mystery Shield portable, and they indicate the new device will be running Android 5.0, which underpins the Android TV OS used in the Shield set-top box, too.
A quick glance at Nvidia's store shows that the current version of the Shield handheld is out of stock right now, so there's plenty of smoke to suggest that an updated portable could be on the way. We'll be on the lookout for the new device if and when Nvidia announces it.
