WinSPMBT originally ended in 2020 and was extended to 2025.

As to what happens in 2025 that depends entirely on Don and Andy.

BUT !
Given some of the recent tech that's becoming common place (mini-drones, various anti-drone systems, artillery/missile intercept/destruction systems, electronic camouflage/invisibility, robots, cyberwarfare, etc.), stuff WinSPMBT was never designed/coded to deal with going beyond 2025 with the sort of tech/capability accuracy WinSPMBT is famous for would be VERY difficult as it would require basically redesign/coding of the entire game.
So don't hold your breath.

(Note: This is ENTIRELY my opinion and has zero input from Don/Andy.)
