As with any release of XenForo we always get a nice set of new features. Most of the time, some of those features overlap with addons we've once used and can now retire from our forums. When 1.2 was released, I was able to remove about 4-5 addons due to the features added. So the question is, how many addons do you expect to have replaced when 1.3 is released? Of course this is all a guessing game really, we have no idea what new features to expect.
