Latest leak from @evleaks shows Lumia 1020 in yet unreleased Red color with AT&T logo. Though it is not surprising, as we have already seen mass production photos of Lumia 1020 from assembly line. So, may be AT&T and Nokia are planning to bring it bit later. Red has been favorite color of many fans for Lumia 920 and it was one of the hottest selling as well.
Thanks Niss for the Tip. Cheers!!
