Nothing happened. Which was expected as there were no scheduled panels, and all the news happened prior to the con.
It's paradoxical.
They say they want to focus on PAX and do panels there, because attendance at PAX panels is better than GenCon. The argument is that people go to GenCon to play but PAX to attend panels. However, the Adventurer's League has been receiving less and less support at PAX, so that's a self-fulfilling prophecy. PAX is a much more mixed group, rather than dedicated D&D fans.
Really, it sounds like the Adventurer's League is just being slowly downsized. It doesn't make money and the profits it generates in book sales is hard to gauge. But when they cut funds to the AL it's less obvious than when they lay someone off.
It feels a lot like what happened with Living Forgotten Realms, where the program was hyped and hyped but quickly fell out of favour and was replaced by Encounters. WotC really seem to lack the attention span needed to run a prolonged organized play program, or at least run one with D&D.
