Perhaps they'll stop after ATS20. MTM was the last huge album for the masses, not so much as Meteora and HT but many of their songs are highly recognized.
ATS would be pretty much the band's wish to be released, besides WFTE, everyone kinda forgot about it.
Same goes for the remaining records, except for Burn it Down and One More Light, the rest of the tracks are for hardcore fans. The difference between those albums and ATS is that I don't think the band nowadays thinks highly of them, so won't be worthy of a boxset
