Don't worry about the weight issue from Gina's side, she'll be fine. I can't comment on Cyborg's though, as I don't know much about her... We need to have faith in Gina. She knows what's at stake, and what she's doing. So let the weight issues go...
I'm nervous, yet excited about this fight too - I guess only time will tell. Even if Gina doesn't win (which I'm sure she will), that doesn't mean that she's lost. She'll still be a winner, 'cause getting in that ring every time isn't easy, especially with a fighter like Chris.
