No, the synthetic first person singular present tense is still more prevalent, even in Donegal. Overall, yes, Donegal (the only living Ulster dialects, as I'm sure you're aware) tends towards analytic, but they're not that common in some tenses. An Teanga Bheo: Gaeilge Uladh (horrible name, East Ulster was very different from Donegal!) mentions that you can say canann mé but that canaim is still preferred. Same with a few of the persons in the conditional mood.
