Little actual detail is in the news today. They didn't discuss Benedict possibly going to Moscow, but rather the ongoing cooperation between Rome and Moscow on 'ways to protect Christian values in Europe' (Interfax).
As it stands, I wasn't expecting much else from the meeting. If Benedict is going to get anywhere fast with the Orthodox, it's going to have to be with the Patriarch of Constantinople first. Eventually, the Russians will have to fall in line (probably kicking and screaming) if and when serious progress is made with Constantinople or else face isolation.
