This probably pointless, but after seeing the rules for the Mountain King, I believe we can surmise what the stats for our Woldwrath will be when comparing our construct heavies and the trollbloods dire trolls.
Here is what I think:
Range 14 POW 16 Weapon with D6 POw 12 jumps? (Cygnar will be jealous?)
P+S 20 fists
Aoe Ram ability - On hit models within 1" of target are knocked down.
Impervious Flesh (maybe too OP with high armor)
Possibly some type of geomancy
Animus: Elemental Communion
Boxes: 56 boxes
Applied same rules of our constructs lower FURY stat etc. Not sure about special power attacks. Also followed suit of Colossals and how they seem like a combination of existing heavies of the faction (ex Stormwall = Defender + Cyclone + Stormclad).
