Does anyone know when the 1.6 Update will be available for the Playstation 3? Any information will be appreciated. Thank you!

No news yet.

I would guess that for once they are actually trying to fix the extra issues the PS3 has to get it stable and nice for Dawnguard. They have no other reason to delay a patch like this. They would have already submitted it and released if it they were done, and they wouldn't just stop patching it.
