the following is from the Rip Dev Team's blog about the progress of installer 4 for 2.0
Hi folks! Many of you are wondering whats up with Installer 4. No, we havent slowed down the work on it, and are currently in the final stages of hooking the GUI to the back-end. We will be contacting the authors of the major repositories in a few days to invite them into the testing process and to prepare for the upcoming repository changes.
