Hey everyone! I'm working on a map of the new survey world.  So far I have found an Ice Spikes biome!  Assuming the world is a square and (0,0) is the center, the world is 4,000 by 4,000.  This means the SW corner is (-2,000,-2000) and the NE corner is (2000,2000).  That means 62,500 chunks!  Ill try to upload the map as soon as I'm done with this first survey.  Good luck to you all!

At least 2 underwater temples! :3

did you go in the temples.  I found a jungle temple

No, but I'm not even half-way done with the map and there are seven underwater temples.
