One sponsor RIG I'd die for is a Last Exile RIG, but even with the sequel coming to Blu-ray/DVD soon I doubt the series is popular enough for it to ever happen. crying
There's a sequel to Last Exile?!? eek How did I not know this? scream
Last Exile would be my favorite sponsor, too. heart
I would also like a Harvest Moon sponsor; I would hope for companion cowies and sheepies in Harvest Moon style. whee It could also get us some needed farm implements and farm backgrounds as well as cute farm clothing items.
kamen rider, super sentai and / or pretty cure for me * u *
pipe dream never-gonna-happen option: morning musume, or hello! project in general ( though honestly i'd more expect them to put h!p stuff in another music rig or something )
