Aug 4th 2007 2:32AM I'm not even sure it will be a year. Consider this, BC was announced at Blizzcon. ALL they were willing to show at that point in time was concept art. With this announcement we get actual playable zones and dungeons being shown.
I'd guess F&F Alpha will start sometime soon, with a closed beta likely starting sometime late fall/early winter, with an early-mid spring release.
Of course I could be completely wrong.
