I heard she is being considered for Wonder Women
At 5'2", I think she'd be viewed as a bit too small to be Wonder Woman.
As for the clue for the next GBOW... no idea. So I guess it'll be a surprise. Goody! I do like surprises of this variety.
Funny that you guys should mention Wonder Woman. The clue is a picture of Themyscira.
Themyscira > Wonder Woman > Lynda Carter
