Yeah, understandable. I know in the past, some Generations toys were skipped to reserve shelf space for RiD and Movie toys. I don't remember seeing Combiner Wars Thundercracker at stores, and the only time I ever saw Thrilling 30 Legends Shrapnel and Gears was in a novelty shop in Melbourne called Minotaur.
It's not a life or death matter for me, but the only Transformers I'm looking forward to at the moment are TR Broadside, the Jumpstarters, and the 2 remaining Decepticon Targetmaster characters. I think until they shop up at stores, I might go cold turkey for a bit. But it'd be a bummer if those figures don't show up here entirely.
