I'm actually pretty surprised that they just didn't do 00 in any lesser installment while Season 1 was still around and then save the full Season 1 & 2 for the big guns. I mean, it can't be any worse than reusing SeeD. I mean, it was Seed in @3, W (Although, that was Astray wasn't it?), Stargazer for K, and Seed D in its entirety in Z, and now Seed and Seed D again?
Also, while Gurren Lagann would be crazy insane, I have to wonder about all those rumors floating around on the web concerning a "feud" between Banpresto and Konami (which I guess has some stake in Gurren Lagann). Eh, probably nothing substantial if they have the money, like what I'm guessing was the case for EVA.
Coming from some one who stupidly watched the entirety of Macross Frontier... No more Ranka... NO MORE.
