Dota 2 patch drops Elder Titan hint, speeds loading by up to 50%

The original patch for the test client clocked in at over 1.5GB. That resulted in a wave of excitement and panic. The patch notes revealed that the download size this was due to changes to the file layout of Dota 2, not the addition of any outstanding heroes. 
Alongside the file format changes, Valve have added new chests that contain some of the first HUD skins. They appear if you’re lucky enough to find a chest for either Morphling, Omniknight or Kunka. So far they include the Dire, Radiant, Diretide and Frostivus HUD layouts. Also added is a new chest named “Treasure of the Forbidden Lotus”, which is probably themed around the Chinese new year.
But there’s a bigger mystery. Our friendly neighbourhood patch devourer, Cyborgmatt, has made a very strange discovery. While checking the status of the unreleased heroes and their textures in the patch, most could see that Tusk’s materials and particle effects were pretty much ready to go. But there’s a new set of textures included: named the “Elder Titan”. Some speculate that it could be the Chinese version of Skeleton King, in which skeletal or bloody depictions are forbidden. Others believe it could be a hero we already know that has been renamed, but no one has made a credible link. 
Then there is the other possibility, that we could be looking at a brand new hero for Dota 2.
Exciting! Here are the patch notes:
