So the return to both article confirms 4 player skirmish. Are we likely to see extra maps with figure packs? It's hard to imagine 4 players on current maps!

You're right about current maps -- which only have two setup spots -- not being appropriate for four-player skirmishes. Maybe once four-player is actually in place, ally and villain packs will come with one two-player skirmish mission and one four-player mission, instead of two two-player missions.

I'm very excited to see how this all pans out. particularly if there's going to be a new mode of organized play for 4 player tournaments.

Very interested in 4 player skirmish, just wish there was another faction.

Will this be two on two or would it be one imperial player and three rebels?

Sounds like one on one on one on one.
