Kim2311 basically hit the major beats, but the larger context is that DLSFM seems to work in a non-linear fashion. IOW, making lots of headway on Part 2 (the Reeks) before completing part 1 (tentacles). Not really uncommon as a lot of other NSFW creators have this same sort of 'ADD' trait if you will but as we've now seen part 1 is effectively in the bag and he's WELL into part 2 from the earlier previews (9 mins so far for "TMS with Rey FULL Preview Version 1").

Feb 2024: Release a BETA Part 1 - Either more shots or post-processing touchups to come on this release, who tf knows.
So let's crunch some vague numbers:
Part 1: 12 months (Jun-Jul 22' + April 23' - Feb 24')
Part 2: Thus far...7 months (Aug 22' - Feb 23'), maybe 4-6 actual work months remaining. = 12-15 months.
THEREFORE...
Part 3: 1-1.5 years, particularly since this will be the rancor finale and likely a very gory/intense scene.
and then..
Part 3 ULTIMATE Ending: 2 years
Part 3 Ultimate Final Ending: 5 years
Part 3 Ultimate Dark Final Ending Remix Fuck-you-Patreon-Ending.mp4 - 8 years.
Part 3 Ultimate Dark Final Ending Remix Fuck-You-Patreon-It-Was-All-A-Dream-Ending.mp4 - 12 years.
