first of all, I think comp.lang.c++.moderated is a better place to 
discuss things like that.

then, I don't think the next version of C++ will have properties as a 
language feature.
see n1615 for a few arguments by comitee members.
I don't agree with all of them but the most important is: without 
reflection, properties are only a syntax change of something you can 
achieve without properties as well.

this paper also proposes a library solution without core language 
extension you might be interested in - although it has drawbacks like 
implementation pointer overhead.
