It's a fear a lot of us share until a prize bey is announced :p.
Yeah, somehow I doubt we'd get a bey named "uranus", we'd get whatever equivalent god there was (I forget, I'm sure someone will remind me in a minute). A uranus cw would be awkward with many wheels, one in particular, of course. I guess seeing as we're a child friendly board, we should stop discussing this now
So yeah, as for planet wheels/beys, we have
Mercury Anubis
Quetz (Venus)
Earth, I guess
Vari Ares (mars)
Jade Jupiter
Scythe Khronos (Saturn).
I think we were only supposed to get 4 planet beys, weren't we? (Quetz and Earth don't count in the tv show, but yeah). Still wish anubis would see a wider release, though considering how heavily it features in the anime, I guess it wouldn't be unreasonable to expect hasbro to release it eventually.
