Could I still somehow back you folks?
Paypal has been shut down. I think the next chance would probably be Steam Early Access. If GOG supports alphas/betas in about a year, then the D:OS 2 alpha/beta will be available there, as well; otherwise it will just be Steam. I don't know if GOG may add some kind of Early Access type system, or if that will just be available to Kickstarter/Paypal backers.
