I believe all/most of that is being worked on for 7.3, check the changelog
I hope we consider expanding the usage of the profile page in coming versions too, including the blog and recent images in the gallery. One thing left would be to show 'buddies' in there and have a personal guestbook others could leave comments on. It's a natural progression for the profile and one that would push .threads to leap-frog myspace/facebook in functionality.
Default profiles to not be viewable by the public and allow the users to decide if they want to 'publish' their profile page.
