I suppose with Magnus being incapacitated, Sentinel Prime is the next in line in terms of being eligible to become Magnus - but perhaps there still needs to be some electorial process to actually promote him to Magnus. I wonder who Sentinel's running against or if it's one of those bogus elections where there's only one candidate.
Maybe Sentinel is the new "Emperor of Destruction"
