Privateer Press has a preview up of their final Warmachine colossal, the Galleon.
From the preview:
The raw might of a naval ironhull now walks the lands as the Galleon. The colossal fires a rolling broadside before reaching out with its enormous cargo claw to toss warjacks like rag dolls. It can also use its massive trident to reel in foes and finish them off at close range with a series of punishing blows. The Galleon commands a high price, but for those mercenaries who have the fortune to spend, it fights as a symbol of unquestionable affluence and might.
