If you have kept an eye on your Wargame Vault notifications you will notice that Rogue Hammer is getting updated pretty quickly.

What I am doing is I have a big list of the various armies to cover and each day I try to tackle one part (infantry or vehicles) of one army for one edition. So today was the Squat infantry for Rogue Trader for example.

The for sure plan at this point is to cover the following:

Rogue Trader armies that had army lists.

2nd edition codices

3rd edition codices (possibly only Tau and Necrons)

Any units and army lists from the RT and 2e era White Dwarf

Any units and army lists from the era Citadel Journal

Selected vehicles from Space Marine 1st edition.

Now this does not mean every single unit will receive a Rogue Hammer equivalent. Some units may be merged together, others may be split. But all will be considered. The priority is to make it all fit into Rogue Hammer.

Likewise, it is important to note that this is creating the units in Rogue Hammer. They may feel different, have different abilities etc. Think of it as a parallel universe where GW never released those dreadful paint pots that dried out in 2 weeks. 

After that there are many options that MIGHT happen. They include:

Army lists to use ww1 and ww2 armies.

Army lists for other "old" wargames like Void, Warzone and Vor (in particular). 

Some television and film units, mostly for scenario fodder. 

I guess this would be the "Rogue Hammer Expanded Universe". We will see and it will depend on what the fans want ultimately. The priority is the 40K stuff.
