Looks like iSims obtained a few pieces of artwork (as well as two screenshots) of The Sims 3 Late Night 2 Showtime from EA Germany’s Origin Store.  They’re a bit on the small side, but we’ll see high quality images when EA gets ready to announce the expansion – which should be very soon – perhaps even this week, maybe.
