The 2014 patch will be released before 2015 version. But we want to make sure that a) people who don't want to buy the new version still get the new match engine and b) people who wait for the new version don't have to wait until Summer 2016.
Again, promising the match engine patch for 2014 was (hopefully) the last time we made such a mistake. In the future (and I guess you already can see it) we will be much more careful with any kind of promises.
