My current plan, assuming I finish before the EE is released is to release for both.
If yours is playable, it wont hurt anything to release it for the current version. And then have your own EE for the EE
if you are still interested.
I would not expect many players though out of the pre-EE version but who knows. There's still like 1000 people at any given time playing D:OS. D:OS non-EE will remain a separate entry in everyone's libraries so modding should have a clean slate workshop for the Enhanced version.
If you need any help squashing a bug that's particularly nasty and showstopping, I can take a look at it if you want.
