It looks real to me. Our friend Rob from Phandroid has posted some pics of a T-Mobile myTouch 3G running a test version of the Android 2.2 firmware. Not a lot of new information was revealed, but image gives us a preview of a newer Android Market.
It appears the next update to the Market will allow for automatic updating of select apps. A check box is located on the app detail page which allows the user to toggle this feature on and off. This was a major gripe for many Android users, so it is nice to see Google address it.
