I really can see Donna Vivino taking the role to Broadway - as RJ said, it simply seems like it would make sense. That said, if she doesn't, I see Anne Brummel kind of being a longshot - but then again, they bumped Marcie from San Fran standby to Broadway lead, so it wouldn't be the first standby from another production to be bumped to the lead on Broadway.
Seeing as the tours do have a habit of promoting ladies, both from standby to lead and understudy to lead, I wouldn't be shocked to see her take over the 2nd Tour, nor would I be completely shocked to see Jenny DiNoia take over 2nd Tour. As for Broadway, they really like to recycle - so my guess would be a former lead.
