TBH, I thought their getting into GPF was practically a given. The only thing that could have stopped them would have been lack of sufficient time to prepare for the new season, but luckily it looks like this won't be a problem. My only worry now is the possibility of Yuko getting re-injured once they start doing quad throws again.
But I agree with you that Tarasova/Morozov and Zabiako/Enbert deserve their chance too (as do Astakhova/Rogonov, but unfortuately both their events look difficult).
Hope Yuko stays healthy. Really hope to see them at Skate Canada.
