I think that they would make Ronda win at least one fight before giving her another shot. They need to keep introducing new faces (likely Alexis Davis, Meisha Tate, and Sara McMann) that can contend. The UFC needs the public to think that there are multiple legitimate title contenders in the women's division, so the belt changing hands a few times cant hurt.
Liz Carmouche seems like a very marketable and likeable champion, and has definitely gained a following through her Primetime appearance. I think the UFC would have no problem going forward with her as champion, although they surely plan to get Ronda back into contention ASAP.
