You are right, forgot Torres.
Though to me at least it seems like there's no clear MeeGo leader as the Maemo/MeeGo has grown so much inside the company.

Imo whiles Torres and Elop might be painting the big picture, much of the stuff we will see on Nokia's MeeGo will be from Ahtisaari as he lead of design and user experience and has been at least been actively talking about MeeGo, where's Skillman works for him (Ahtisaari).
There's actually rumour going on in mobile-review forum that the UI has changed hugely in couple of months after Skillman came in.

Just my thoughts.
