Jon Zuk, the lead designer of SoF2 updated his plan file, saying the following
We're working hard to make SoF2 as mod-friendly as possible. Eventually we'll release docs and tools for everything. But skinning is fairly independent of everything else and something good to get started with. Things in SoF2 that can be modded without any coding:

Maps
Skins
NPCs
Weapons
ConfusEd entities (our custom world model system)
Effects
Scripts
RMG
MP game types

There's probably more that I'm forgetting, but you can see why it will take us a bit to get docs for all of it.
I know thy are different games, and different teams working on them, but Its the same company and they are using the same engine and technology
Someone posted in other thread that we wouldnt be able to edit weapons without the SDK, but It looks like everything will be easily editable in SoF2, lets hope JO will be similar

Good glad to see this- helps with staff planning :)

I sure hope that's true for JO as well... that'll be SOOO sweet...

wow! That means we can do anything pretty much! Force flying, here I come!!!
