Is there going to be a new GUI for Appium 1.6.x?

I recently got informed that SauceLabs is developing a new proprietary GUI for Appium, and seems that they’re charging for it: https://saucelabs.com/resources/webinars/An-Introduction-to-Appium-Desktop

Will we have a new GUI for Appium 1.6.x? Or do we have to consider going with the paid one if we want a working inspector?
