seems you have misinterpreted something, (another case of wishful thinking perhaps) the foundation
never gives fixed release dates.
Also "the second half of 2014" (I assume you are referring to something like that) runs up to december 31, but even for this timespan no release promises will be made!
basically, when its completely ready its ready, and the day after the world will probably be informed.
then again, I'm not an official spokesperson of the RPF, just a moderator, so everything I'm saying is based on educated guesses, nothing more and nothing less.
