I couldn't help it, I got the Rosalina one. I pushed myself not to... but I couldn't resist i'm so ashamed of myself
Also part of the theme shop update is the ability to take screenshots of your home screen, a good options menu (where you change the brightness), and now the eShop has the Wii U's theme. At least, I went on the eShop and heard the Wii U eShop theme. There's probably also bug fixes and whatnot.
