It depends, I thought a break was due after Bounce, and in a sense it was a break, while there were stuff released (TLFR, box set) and some promo done for each of those releases there wasn't any touring involved or an albums worth of new material, and they sometime off from the band to allow the band to take a breather.

I'm guessing if there is a break, it will most likely be one like that, maybe a bit longer.
I'll say 3 years tops maybe??

remember also, there really wasn't a plan for a 5 year break between These Days and Crush, it was originally supposed to be a 2-3 year break.
