Since GW has broken with the standard USD125 price point for their next boxed set, perhaps this means there is a great deal more flexibility in what can be included in the future. Also bearing in mind that they have finally stepped away from the "include 2 troops, an HQ, and something else" model. With those factors in mind, what combination of armies and units would you like to see?
I have included a few options based on the standard "Imperium vs. Other" model that has worked so well for GW so far, but if you don't like the options by all means suggest your own!
