I've never strongly attached myself to a particular developer in the first place, so this hasn't really affected me so much, though probably I'm most attached to BioWare now, mainly because they have two game series I really enjoy.

As for Square Enix, I've always been a fan but my gaming horizons have expanded far beyond them at this point. There's just so many game series besides Final Fantasy that I enjoy now. And that's a good thing.
