They did such an awesome job with the finales though with pretty much the perfect ending with Leslie as Governor of Indiana and Ron as Pawnee National Forest Park Director. Gonna be near impossible to top all of that.
Yeah, it would have to be some sort of special, rather than an actual revival. And if it were ever to happen, and done perfectly, there could be a chance for more specials to be made at any time. Think those not as known webisodes (like where Andy and April road trip to the Grand Canyon), but bigger and better.
