As far as I know the DA2 toolset is exactly the same as DAO's with only minor in-house improvements. "'The tools we're using to make Dragon Age 2 are very, very close to the tools you guys have used to make your mods for DA:O. They're not identical, as we've made a few in-house improvements, but they're almost identical. As such, there isn't a new toolset to release, per se.
