The list is out and can be viewed under Leagues & Ladders > Grandmaster.
Apparently you have to play 1 match more and if you're grandmaster they will put you into this new league.
Your points will be reset to about 200+ but your stats will remain.
My first thought - The Grandmaster icon looks way better then the masters icon.
My second thought - Wow even more hurdles for players if they want to get to the top of GM. For e.g if they ever fall out of GM and decide to start playing again, they have to wait a week to get promoted to GM(not sure about this). Then they lose all their points and have to start again climbing again from 200+. Not cool at all the "XP Decay" feels like too big of a obligation/commitment if you wanna maintain GM status.
Along with the GM list comes a new patch which is more of a bug fix than anything.
General
Fixed an issue where maps would not appear in the Single Player vs. AI screen (China only).
Fixed an issue where the Leagues & Ladders Friends page would stop displaying information if a player had more than 100 ranked friends.
Fixed a crash that would sometimes occur when players received an alert in-game while 3D portraits were turned on.
StarCraft II Editor
Fixed a crash that could occur on Editor startup if players had improperly configured variables.
Fixed an issue where the Editor would display incorrect cliff height on ramps facing directly N, S, E or W; this issue prevented proper unit vision in game.
Fixed an issue where the pathing visualizer in the Terrain Editor would sometimes display incorrect pathing.
