From the sounds of things this will be supported for a very very long time moving forward.
The terrain below is all in plastic, and it looks fantastic as well, love that they have all of this ready to rock for release!
Not sure i will be buying into it at first drop, but I know I will be playing it in the future, its amazing.
I did get to hold a Warlord, one of the designers let me grab a hold of it and have a look, and they are fantastic models (as you expect from GW now), but its not a model for beginners.
All the models look pretty snazzy and I look forward to seeing it on the table top and getting some games of it under my belt!
