I'd say the plan is to continue what we're doing now, updating and maintaining the current version of FF, but also start making a sequel of sorts.
Basically, I see a sequel being "the ultimate TF game" with lots of modding capabilities and extensive workshop integration to where we have a base "FF2" made as well as some kind of mode swapping to play original FF as well as TFC and even QWTF. You could get a workshop mod of FF that let's you play neotf for example. Or more specifically, I see me making a hunted mode that's a more involved hunted style not in the default version of FF, like with civilian AI, singleplayer, cutscenes, etc. Not just a map but a whole game of its own.
There are more thoughts in
the old roll call thread.
