Why not? Scott is 40 and still plays in OG, so why should Gamova not do it with 36? She doesn't have a family like Sokolova and Estes and she never took a year off from NT and she never had any serious injury, so I can imagine she will continue unless she wins the Gold she wants to much already this year.
After this quadrennial, I think Gamova should be only called in important tournaments like WCH and Olympics. Of course, she has certainly done a lot and can still do just a little bit more for Russia but she won't be in NT forever so Russia has to learn not to rely on her always in future games.
