The TES IV GameInformer unveiling contained a number of in-game screenshots and a ton of feature discussion and Oblivion wasn't nearly as far along as Skyrim is at the moment. The FO3 unveiling in GI was similarly detailed so I don't expect the Skyrim article will just be concept art and GI speculation.
There is also already a http://www.gamesas.com/index.php?/topic/1151387-the-february-game-informer-cover-thread/ about this.
Yeah, let's continue this in there.
