At least Toshirou looked cool in that hollow bankai mode... The only good page of that chapter.

Also, your theory fits, after GMG, we had (at least) 3 arcs left till FT's end and if Sun Village was to be considered as one arc, then Tartarus arc, final arc aaand we're done. This may also mean that the anime will be able to fully finish the series without any further interruptions.
