will, would

[joham]

This sentence comes from MACMILLAN DICTIONARY:
--Sylvia said it was your fault.
--Well, Sylvia would say that, wouldn't she?

My question is: Can we say 'Sylvia will always say that, won't she?' without changing the meaning? When criticizing someone's typical behaviour for a particular action, do we always use 'would' rather than 'will'?

Thank you very much in advance.

I prefer the sentence from the Macmillan dictionary. If you use 'will always say', then for me it extends the context to all such situations whereas would focusses more closely on the specific instance in question.
