Could Rachel Weisz Be The New Lead Female Bond Villain?

According to various websites, Oscar Winning Actress, Rachel Weisz is being tipped to play the new Bond Villain in the next Bond film, so far under the working title "Bond 23". Right now it's just a massive rumor, because the same thing was said about actor, Michael Sheen, who was also tipped to play the villain in the next Bond film. He was rumored to be playing the new Blofeld, which would be amazing, but turned out to be false. So, if this is true then it would also be so amazing, because we've never really seen a female actress playing the head Bond Villain in the film. The only female villain that we always see is like the main villains wife or girlfriend, that's all really. So it would be good to see this for a change. 

Surpposedly she's gonna be playing the head of the organization, Quantum, which is mainly the centre of Quantum of Solace and Casino Royale. (SPOILER ALERT for those who haven't seen Bond 21 & 22) So basically she's the person that really killed Bond's lover, Vesper from Bond 21. BITCH! A bet Bond will be so pissed to find out that the true villain is a female. I'm not being sexist. This is actually awesome to hear. All I can say is, "BRING IT ON!"
