Super optimistic theory inbound!We haven't been told
everything about the game's menu system yet. There's still the matter of the directional compass thingy you summon to navigate the menu proper. Personally I think it wouldn't be too far fetched for the game to include your health, magicka, and fatigue on this display so you can quickly check it without having to go into the full interface. Theoretically, birthsigns/attributes could scroll by here, as well. But I doubt it.
My other theory? The skills screenshot on Gameinformer is just part of the level up prompt, and the player is navigating to choose which skill and subsequent perk they wish to pick. The actual stats menu is far more comprehensive.
I think the article refers to the fact that as your character gains perks the starsigns slowly change.
Which isn't exactly novel. That's how character creation worked in Arena/Daggerfall if you chose to answer questions to generate your class - stars marking the three primary constellations would become brighter or darker until one was the most visible.
