Being a Super Sentai and Kamen Rider geek, I REALLY want to get the Kamen Rider Ranger Keys:
I've got a Mobirate toy, so I'll be able to play with them as soon as I get them.
I might be getting them soon since the same friends from Japan who sent me the Mobirate and several Ranger Keys said they were looking for them for me.
While nowhere near new, I still want one of those 1:1 scale light-up Corps style Green Lantern Power Battery prop lantern. That is probably my holy grail next to a metal Green Lantern ring (I've got the plastic promo rings, I just want something more lasting). Not quite a toy really, but it is something I'd play with.
I'm also eyeing the classic style Transformers toys (I think they are called Collectors Series?) that look like the old 80's toys but have a hefty price tag (cheapest I've seen was around $80, I think).
