Today I got Series 3 Rowlf & Lew Zealand! I was so thrilled! On the back, as with each wave, advertises the next coming wave(ie Wave 4). With Link, Rizzo, Sam, & Dr. Strangepork is First Mate Piggy. Why is she being included w/ Wave 4 when we won't see her til Wave 6? Are she and the Swinetrek being bumped up? If not, why the 6 month delay between Series 4 and its playset? Anybody able to shed some light on this?
