Xbox may be taking its sweet merry time in confirming the Xbox Series S - a lighter, cheaper version of its next-gen console - but we now have "official" evidence that it is coming.

A Twitter user allegedly found a white Series X controller in the wild, in the full packaging and, on the rear, it clearly states that it's available for Xbox Series S as well.

There's also great news for existing Xbox console owners too, and PC, Android and iOS device users, the next-gen controller will be compatible with your machine(s).

If real - and video posted by Zak S seems convincing - the "robot white" controller (bought on OfferUp for $35) is a great indication that the Xbox Series S will be announced very soon. Microsoft is expected to host an event this month, August, where its holiday launch line-up should become more clear.

We're hoping to also find out exact release dates, prices and maybe even pre-order details at the same time.

This isn't the first time we've spotted the white version of the Xbox Series X controller - another appeared online a few weeks ago. However, this is the first time that the Series S has been spied on something that looks like official blurb.

The Xbox Series S (also known by its codename of Lockheart) is expected to be a smaller, maybe digital-only version of the X, but with slightly truncated processing power and specs.
