I see another batch of S7's so likely Batch 12 is my guess. On S7 there was just a lot of leaks hinting it was coming out so I don't think they are going to a new chip or anything huge. One day a S7+ would not surprise me. But I don't think anything super new, if they do they sure did a good job at getting rid of leaks.
I am speculating Batch 12.... but I could be very wrong.
