I'm hawking Amazon and EE for Soundwave, guess I'll add Cosmos to the search. I really like how they've kept the design "faithful" to his original, but changed things up by shifting the proportions around. He was always a bit of chonky boi, but I like how this iteration leans into that.
But, yeah, Earthspark has been winding down for the last year at this point, and I'm concerned that Hasbro is just going to let it what's left wither in retail limbo. And since it's not "Generations", I don't see any of these later figures as being a priority for alternative release venues, much as what happened with the, generally pretty solid (and sometimes better than Generations), Rise of the Beasts Core Deluxe figures. Even Entertainment Earth is pretty sparse on stocking new Earthspark, so I don't know if that speaks to Hasbro's distribution, or the fact Hasbro isn't doing much on the presale side since it's all "kids stuff".
