She will break the record, barring any serious injury. As the CNWT plays 20+ games per, and she is only 25 goals from tying the record, Christine should break the record in less than 3 years. When she retires, she will hold the record, and I doubt there will be any serious contenders for a few years. The upcoming international youth stars of today will be moving into starting roles, and displacing older players that have accumulated goals in the past. It will be tough for a player to maintain a starting striker role for more than 5-6 years.
Wambach is also a goal scoring machine, but I believe her injuries are catching up to her. She looked to be in a lot of pain during the Vancouver qualifiers, and often played only 45 minutes.
