It's also worth mentioning that adding new "purchasable" types (e.g. things like paid resources) is infinity % easier than in XF1. Since multiple payment processor support is built into XF2, we also don't need to worry about things like "does the user have Paygates installed or not" when displaying purchase options.
As a developer, the experience is just vastly more enjoyable.
The point I'm trying to make is that I expect there to be dozens of new Purchasable types (including the ones mentioned in the OP) either on launch or shortly after launch
