A:SE, the "Scorched Earth" expansion, and the dev kit

Mostly a question I’m hoping the community liason can ask the devs about, but how is the expansion going to affect the dev kit?
Will the dev kit be updated with all the content? Will we need to buy the expansion first to use it? Will our mods or maps be compatible with everyone or are you splitting the community a bit here?

The SE content will get released to the DevKit in a couple of weeks, considering it will be the source assets no licence restriction can be applied.

Everything’s compatible and will be, but presently they clearly made some core changes as ACM is currently broken until I get new classes to compile against.
