I really want to have the latest 1.9 patch. Mostly because of the new legendary difficulty.
Have the official release date of the patch been announced anywhere?
And if I try out the beta, how high is the risk it will mess something up? I mean, I use a lot of mods and it have not caused to much problem. Is the beta warning a real warning, or more of a "failsafe" to make sure they dont get to much crap if something goes wrong?

More of a failsafe.

1 more week until its official. Hopefully.

I fear that it will destroy mods even further.

How so? Please elaborate.

Most patches that came out always messed something in already existing mods.

I don't mod skyrim. I wouldn't know
