[Spoilers C4E27] Potential run time of Campaign 4

Is anyone else wondering how long this 4th Campaign is likely to last...?

I know the other 3 were like 2-3 years long right? But Matt's style of campaign is quite different to Brennan's, and the format of the campaign is very different. I mean it's been 27 episodes and we have covered like, what, 10 days of in game time? So it could go on for ages if it keeps up this rate.

But I'm also unsure. Like this is an extremely dramatic series of events all coming to fruition. How can you keep that pace up for 2-3 years? I get the feeling it could be over a lot sooner?

Can we even envision the endgame at this point? Do we know the terms and conditions of the campaign's climax? Who even is the BBEG?? Is it Primus? Wic wants to take down Halovar/CC? The party will need to level up a helluva lot to do that though I guess?

Does anyone know if it's been said in any of the BTS stuff if there is a clear direction? Maybe Brennan planned for this first big arc and maybe if the reception was good they keep going?
