The iPad figures ship in a case of 6. 2 each of Frankie and Draculaura and 1 each of Clawdeen and Lagoona, that's why those two are harder to find.
As for the Bratzillas... The webisodes dont's seem like they're going anywhere though they are a huge leap up from the Novi Star "vlogs" (talk about a bunch of airheads... wow...). I would expect at least one more Bratzilla dolll. There's a male character in the live-action music video and the webisodes (name eludes me at the moment) with skull tattoo/make-up covering his face that's playing a fairly prominent part. There are alse two "mean girl" characters that could possibly make the cut as exclusives if nothing else.
