"I just don't know," she tells the latest edition of TV Guide.
"I love my job. I love NBC. When the time comes when I feel it's right for me, I'll figure out what I want to do, whether it's continuing to do what I'm doing or try something new or do something crazy and totally different."
Couric, 48, confirms that she was approached by CBS News about taking over "The Evening News" after Dan Rather retired.
But "there were no serious talks," she says.
To compare the two female anchors constantly is "sexism" she says.
"It's interesting that they never compare ['Today' co-anchor] Matt Lauer and ['GMA' co-anchor] Charlie [Gibson]," she says. "There is a level of sexism in these discussions.
"I hate to pull that card because you don't want people rolling their eyes. It's just a fact of life you have to deal with. Diane is great. I don't know her very well, but she seems like a great person who has a good perspective on all of this."
"Today" recently hired a new executive producer, Jim Bell, and Couric says since he's come on board, the show has been better.
"I think the show was overly scripted," she says. "It didn't give us enough down time to chat, relax and be ourselves because [the producers] were trying to cram in so much."
Going forward, Couric says she wants "Today" to focus less on "splashy, tabloidy stuff" and more on serious issues.
But "TV seems to shy away from things that seem dry," she says. "But I think it's our responsibility to make it interesting and to engage people."
