It probably won't happen, but I hope Larson-Green gets the job permanently. I like her apparent influence on products and if she can indeed, as Ballmer put it, "effectively collaborate and drive a cross company agenda", that might help stop the whole internal competition thing going on right now. Of course, I have no idea if she's able to deliver stuff on time without too much trouble like Sinofsky was able to.
Also, I'd just like to see a woman as the lead. The whole "it should be the person best suited for the job regardless of gender" argument is nonsensical. Of course it should be the person best suited for the job, but it would be preferrable if the best person was a woman. There's an embarrasing shortage of female rolemodels in this industry, so if one was to emerge, that would be a lot better than yet another male rolemodel.
