The wave with Destro, Lowlight and Shadow Tracker has never been stocked here either.
Monday night there was a new case of wave 6 which is the one you saw, Jesse, with Iron Grenadier, Viper, Crazy Legs, Croc Master and Snake Eyes. I picked up both Viper figs and one IG, the other was gone when I got there. I really like the IG figure, he's basically Destro with a new head. The Viper is okay, but I don't like his rifle and the left arm is lacking some range of motion in the elbow which is mostly due to a design problem.
I've seen at least one report of wave 5 showing up and seems to be coming after W6. Wave 5 has the masked Cobra Trooper, Steel Brigade, Hawk, Blowtorch, Cobra Commander and Jungle BAT. I'm looking forward to Hawk and Steel Brigade from that wave but I'm not sure if I'll pick up the Cobra Trooper or the others.
