...and pretty much any other G1 Transformer I don't already have.

I don't really expect TakaraTOMY to reissue most of the Transformers on my list. Considering how badly Encore Sky Lynx, Metroflex and Omega Supreme have shelf warmed I wouldn't blame TakaraTOMY for not wanting to reissue more big expensive reissues. Does anyone know how well (or badly) Encore Bruticus has been selling?
