As much as it pains me to say this but I think the leak about no Penny's scene makes sense. 3 H-scenes are announced for this update so there must be someone who we anticipated to get a scene (Luna, Nova, Penny, Nancy, the 4 who got a scene in 0.5 and was skipped in 0.6) not get it this time around. From the poster we know almost certainly that Nova and Luna got it. Then it is 50-50 between Penny and Nancy. So I guess is there might be a lot of Penny involvements in the stories this time around, get promised a date with her next update, while Nancy got a scene, to balance things out.
Still it doesn't diminish my excitement to play 0.7. For that I shall swiftly begin my prayers and offerings to the nameless God of Leak for the arrival of a destined hero around in a few hours.
