Skaven update rumors items missing from website

The rumors for the the next End Times book is supposedly about the skaven and some new model release are to come with it. I have wrote before about what i would like to see in the update but i just might have found some clues. When i checked the GW site tonight there are
5 items either sold out/no longer available or temporally out of stock! Grey seer Thanquol and Boneripper and the warlord model are sold out/no longer available and Warplock jezzails, Rat Ogres and Giant Rats and the Doom-flayer are all temporally out of stock. Hopefully this is a sign of whats getting updated (YAY JEZZAILS!!) or maybe it just me looking into it to much? I live in Ireland so maybe it might be different on other countrys site but its worth checking on
