There is a new rumour floating around:
It sums up to: GW will not cast any more models of the Specialist Games range and once the stock is sold out, there will be no more models available over the GW-Website. Some of the Warmaster-Models are supposed to be unavailable already.
If this is the case, would this really have such a great impact on MH? I personally have never bought any MH-models from GW directly. Taking the rules off the page might hurt us more. Even if they are available on the web if you know where to look, new players tend to look at the GW-page first.
