Engadget reports that the elusive adapter was recently spotted in Asda, a UK supermaket branch. Asda has the adapter priced at £49, which is in line with the older model.
Microsoft has been vague on the release of this new adapter, but it's real and here now in retail stores.
For those of you who aren’t familiar with Asda, its a supermarket chain that was, until a couple of months ago, owned by Walmart. So speculating that we're not too far away from a U.S. release couldn't exactly be considered going out on a limb.
