Lexicon announced on their Facebook page that they are working on AAX updates for all their plugins.
Next to the AAX support Lexicon will extensively examine and rewrite the source code where needed to improve security issues that can hog the plugin due to many calls to the iLok. The new plugins should therefore be less resource intensive. Mac users in particular should expect a better performance as the code for the Mac plugins will receive improvements.
Lexicon hopes (but doesn’t promise) to have Beta versions ready by NAMM 2014 which is late January or the beginning of February. A final release could then be expected approximately 30 to 60 days after.
