What happened to Ironjawz?????

I went some years ago to the shop with my older brother to buy a Soul Wars box as a gift and liked a lot Ironjawz Start Collecting box and thought "i would do this army". Then some years later i find out i have now adult money. I arrive to the store and all the orks are skinny weird guys in vultures. Ironjawz are way cooler for me what happened to them they are not a thing anymore?
