Hi @drd, no a member login system is not part of this next release. The feature being released is updated “site” and “per page” password protection.
I cannot give you a timeline yet for member login feature, but a lot of the platform improvements in this next release pave the way for more features like this to be added 
Stay tuned at the wish list here: Creating a Membership Login site with payment options - #2 by Revolution
I will be cheering together with you when support for that is added
