Galadon confirms all the info.
TH13 info so far…

– TH13 will have an inferno tower on it and retain the gigabomb and adds a freeze effect on explosion(after level 3).
– New level troops are; Electrodragon, Dragon, Balloons, Healers, Wallbreakers, Bowlers, and Hogs.
– New level of spells are; Heal, Jump, and Skeleton.
– New level of buildings are; TownHall(duh), Eagle Artillery, Xbows, Inferno Tower, Laboratory, Storages, Tesla, Barracks, Wizard Towers(2x?), Cannons(2x?), and Air Defense.
– New defense: Scattershot.

– New level of walls.
– New levels of mine traps.
– New hero levels. (Assumed 70/70/50/20)
– New hero (Royal Champion, targets defenses, hops walls, ranged attack, special ability is a chain reaction with no range limitations).
– New troop (Yeti).
– Camps are 4×4 instead of 5×5.
– Lab is 3×3 instead of 4×4.
– Workshop is 4×4 instead of 5×5.
– Storages increased to 18 million and DE storage to 300k.
– Grand Warden’s Eternal Tome doesn’t grant full immunity to the effects of the Giga Inferno. While Eternal Tome may protect your troops from any damage that may be caused by the exploding Town Hall, it does not prevent your troops from being slowed down by the icing effect from the Giga Inferno’s explosive demise.
…Will edit and update as people post more info in the comments.
