In addition to announcing the new Shield Tablet, Nvidia is also working on an update for the Shield Portable hand-held gaming console which should be available with the Shield Tablet launch and bring several new updates including support for the new Shield Wireless Controller.
According to an official presentantion slide, the Shield Portable should be getting support for the Shield Wireless Controller, something that was already obvious with the announcement of the Shield Tablet. The new Shield Portable software upgrade will also include updated onscreen controls, some GameStream enhancements as well as the new improved Shield App.
We are still not sure if the Nvidia will release the new Shield Portable OTA update on July 29th, when the Shield Tablet will officially launch in the States and Canada, or will the update start to roll out as of today with the announcement of the Shield Tablet. In any case, those that own the Shield Portable should be getting it shortly.
