I suppose 2014 makes sense, especially considering it is now less than one year away. I have a hard time imagining that they can pull it all together in time for the holiday season, and after the fallout from 4E's (too early?) release, I can't imagine them wanting to rush it this time around.
What we might see, however, is some kind of beta Player's Handbook or rulebook - maybe even for GenCon this year. Right now we're not even in an alpha phase, as in a consolidated rules document, so we're a bit far away yet. But I could see something more complete this year, even enough to play an ongoing campaign with minimal changes when the official rules come out.
In other words, there's a period between when the rules are 90% finished and the final tweaking takes place; that could take six months or a year or so and requires at least a beta book for people to pore over.
So while I'm looking forward to a finished product, it may be that we'll get something close enough to play sometime later this year...or maybe that's just wishful thinking?
