This came in today. This is officially being called the Harry Potter set 5. I have no idea what happened to set 4 because there is nothing yet up on Neca's web site about set 3 or 4 or 5, but Big Bad Toy Store has set 3 and 5 up for Pre Order now. Set 3 (Bellatrix, Lucious Malfoy and Harry in Casual Dress) coming in this Month (Delayed from January) and the 5th set coming in the third quarter of 2008. Maybe after the big meeting going on in Las Vegas for toys companies and studios for toy licenses, we will get some news this week.
Anyway set 5 is Fred and George Weasley and Mad Eye Moody as seen below:
