That's quite an old article - Jane hasn't presented the 11-2 shift on BBC News since 2012!
It wouldn't really surprise me if Jane jumped ship the way Sian Williams did. I know she regularly did the One before her absence but once George Alagiah is back properly on the Six Sophie Raworth can go back to the One and the only regular slot for Jane will be the Five on Fridays.
Even before George had to take his second leave of abscene, sadly he was rarely presenting four times a week. I could see the Six becoming a job share between George and Sophie, with one of Reeta/Jane/Ben taking over the One. I don't want to turn this into a fantasy rota post, if anyone wants to know my thoughts on that, I'm willing to talk via private message
