What do we know so far about SkyrimSE compatibility with existing mods?

Will an ESP from Skyrim work with it?

Will NIF files from Skyrim still work?

Will Skyrim version of NIFScope still work?

A biggy - will Fore's New Idles work with SkyrimSE?

I expect BA files to still work - I think Fallout 4 has backward compatibility.

Which Creation Kit will we use - Skyrim or Fallout 4?

SKSE will not work until a port is written for the 64 bit engine. Any idea how long that will take?

Mod Organizer for Fallout 4 should work since it has 64 bit engine support already.

If there is a topic - somewhere - with these answers, I would sure appreciate a pointer.

Nothing will work, because if you can't understand all the answers that have already been given, you won't be able to install anything correctly.
