Rumours have been circulating for the past few months regarding an ASUS ROG gaming phone, with the company's CEO Jerry Shen hinting that such a device should be "expected" at the opening event for their 100th retail store in the Philipines ( link ).Now ASUS' Republic of Gamers Twitter account has released an image of what could be ASUS' upcoming Gaming Smartphone, a device which can be docked onto a dedicated controller to offer top-class mobile gaming experience. This is just speculation on our part, though it seems like a logical direction to take, as a gaming smartphone needs to be paired with a decent gamepad.Looking at the top of the image, we can see telltale signs that there is a front-facing camera on the screen of the device, making it seem unlikely that this is an ROG-branded gamepad for PC.
