>>56902537If you look at the trend of Sleepdex goals, every new goal increased area bonus by 5%, except for the current last goal of 390 sleep styles which gives a 10% bonus from 65% to 75%.
The datamined cooking pot upgrades also only go up to 84 so far (+15 / 5*+3 from 69).
That part doesn't quite line up though, since each Sleepdex goal gives two cooking pot upgrade unlocks, and previously datamined cooking pot upgrades were also changed so this part is equally subject to change.
The key part is that each map unlock is separated by one sleep dex goal, with the most recent being Old Gold Power Plant at 340, and 390 being the current last.
You can study this and extrapolate out probable key milestones:
>440 sleep styles: Dragon/Bug/Poison Island, Max Map Bonus 80%>490 sleep styles: Max Map Bonus 85%>540 sleep styles: Final Random Island, Max Map Bonus 90%>600 sleep styles: Max Map Bonus 100%Though this would end on a cooking pot capacity of 93 if each goal gives 2x +3 unlocks. So, unless the last two instead give 3x +3 unlocks, there might be five additional Sleepdex goals rather than the 4 I've considered here.
The game has suggestions that they want to end on round numbers, ingredient and item bag maximum storage will probably finish on a round 1000 similar to Pokémon storage.
I get the impression that they're going to drag their heels on these final few unlocks now to artificially extend the lifespan of the game, and keep the research rank/level cap unlocks in-line with those ingredient space upgrades.
Next new island could have a new cap of level 75 or 80, final island could be the level 100 final cap.
There is after all only the two subskill unlocks after level 60, and the EXP curve will be so high that it takes ages to get there. The level curve actually would mean berry strength would probably be more valuable than the subskill unlocks themselves in many cases.
