I'm sure the new guy will do a fine job. I'm just not interested because Brubaker is the one who established Winter Solider and the relationship with 'Tasha in the first place, his writing is what makes the dynamic in the book so compelling. I'm just not interested in another writer. To me this was Brubaker's book. It has his stamp and work all over it.
I almost feel the same way about "Fantastic Four" and "FF" but am giving Fraction a chance because I've like some of his stuff in the past.
Action Comics will be the same over on the DC end ...depending on who the writer is that succeeds Grant Morrison, I might drop the book entirely.
