Just preordered a Wave 4 case of Generations Series 4- Warpath, WheelJack, Thundercracker, Kup and Scourge because I don't want to miss out on those guys. I will most likely share the love and put the extras up for sale but I'm not making any guarantees (Or sale threads) until I have them in my hands.
and I saved about $25 bucks in the deal too, so I might be sold on the whole preordering thing.
