I suspect Deluxe and Collector's edition are never coming back in print as Funforge had a really rough go at this when they got it produced with endless delays and complaining.
That's too bad because it's a fantastic game. I missed the Kickstarter but I bought the retail edition and later the deluxe when it was available on Amazon. I also have the expansions and additional minis.
They do plan on reprinting the expansions this year to match the 5th anniversary art design. At least that's what I heard last time I asked them about it.
