Would Mantic have any intentions to make a model range equivalent to Space Marines?

They gave us 'Space Dwarves' because the demand was there among 40K players. Yet there is also a demand for Heresy era marines, even Primarchs etc. So, would they?

What about 'Chaos', or is the whole Gothic thing out in Warpath's galaxy?
I'd like to see Abyssal ForgeFathers myself...
