Sorry to be the bearer of bad news, but I rang Forgeworld last night, it's gone gone gone :-(
That being said, I like the current model, not as much as the FW one, but oh well. While I am unhappy at the changes, I still think that it's worth it if you have the heavy support slot free - I have found so far that my opponents are more worried about the vendetta, the Leman Russ tanks and my artillery more than a single hydra in my army.
