The headphones will certainly debut at RMAF, I heard it directly from Alex of Audeze at the CA Audio Show last month. I highly doubt that Audeze will delay them for any reason - no vendor would want to miss such a big opportunity to show off a new product at RMAF either, especially Audeze. They did, after all, debut the LCD-1 at CanJam 2009 (the independent CanJam that year,
not RMAF), the LCD-2 at CanJam 2010 (also the independent CanJam, not RMAF), and the LCD-3 at RMAF 2011. So they won't miss debuting another new set of headphones at this year's RMAF.
