This was snuck in with the excerpt on http://www.bethblog.com/index.php/2011/11/09/skyrim-official-strategy-guide-blog-2-sanity-sapping-mapping/#more-17018 (beware there are SPOILERS in that link, I only skimmed it). I am soooooooo foookin glad they decided to do this, I have personally been harping on ad nauseum about how cool it would be to access in-game content while away from the game on an iOS device.
I wonder what else could be included in an app? In-game books? A steam account login with achievements and stats?
