I have an extremely large Multisite installation and do not wish to risk upgrading unless I know the version will remain somewhat current. It was a disaster for me with the back to back upgrades to 3.x. I've noticed the 3.6 and 3.7 versions are expected 2013...is there any idea when those might come out? I'd like to upgrade to 3.5 but will wait if WP is going to release 3.6 or 3.7 first quarter 2013. Any ideas?
