Lawyers aren't quick. They only confirmed involvement last week, so it'll be months before they say anything, if they do at all.
Abramovich stuff has no relevance to this at all, other than showing some of his more suspect activities to the public...and the lack of pick up and fanfare about it shows it won't be deeply or publicly probed
