[Frank Richards]

1) Invisible Woman - She desperately needs an update, but she's a HUGE longshot, since it wouldn't make much sense to update only her without releasing new versions of the rest of the F4 in matching updated uniforms. And, with Marvel having chosen to put the Fantastic Four on the backburner for a while, new figures of the F4 are highly unlikely .
2) Miles Morales
3) Kitty Pryde
4) Rogue - The unreleased version from the Wolverine wave would be a perfect updated version !
5) Storm - Another longshot, since we just got her in the Jubilee wave. However, that figure wasn't exactly widely distributed, so a new Storm wouldn't be entirely unfathomable. I'd like to see a more timeless version of her, since all of the previous versions are all representative of uniforms from very specific era's.

*) Dragon Man - I don't want a new version, just a re-release, like Hasbro did with Kang from Toy Biz's F4 Classics line.
