The release version will be ${project.version} at that point.

Not in sys properties, but I would have thought they were in release.properties (probably several of them, per module). I'm not sure why you wouldn't be comfortable reading that since it has to be there (it's certainly an implementation leak, but not one that seems likely to change).

Other than that, I think you'd need to change the release plugin to pass them to the preparation goals as a system property (though again there's the difficulty of potentially not being the same for every module).
