obviously they will create another 2 albums because they are currently at 4 and there's 6 sides to a hexagon.
albums 5 and 6 will feature a total of 39 tracks for symmetry.
MHtRtC>TCH has 56 tracks on original releases (ignoring japan exclusive and US issue happy cycling) TH has 17 tracks. 56-17=39.
all up there will be 112 album tracks which can be expressed as the sum of SIX consecutive prime numbers (11+13+17+19+23+29).
it can be hypothesized that the last track on the last album will be a backmasking of wildlife analysis thereby tying all albums together in a loop creating an infinite BoC cycle.
from this the band will reincarnate onto a higher plane of existence and begin the process all over again.
