I think "LP ending" in my eyes will be when they stop touring. I love their music, and I'll buy it if they release it, but them not touring would be the end of the band's "time", as it were.
and in that case, I honestly think it'll be Chester that'll put a stop to it - real accident prone, gets ill alot, hell he's already been told to stop jumping off the risers to save his back from breaking to bits so...
that and family, particularly in terms of Chester - he's the most vocal about how band-life strains him as a dad
