This "they should have include fine cast and metal model" is off topic because GW provided both points in the GHB and the renown points calculation method (=cost/number of models/5).
So I must admit that I can't really see a big issue on the matter.
And as Microsoft not supporting Windows XP or Apple not supporting iPhone 4S anymore, it is quite logic that GW does not support some of their old range anymore. More over, it will give some space for their yet to come new revamped factions.
But as Skirmish is being released, maybe this conversation should move from the Rumour topic.
