Nah you got it wrong.
Based on how NLT handled the LE > ToN transition, the main story of the game ends a bit before 100%. The extra stuff after the main story ends takes the game to 100%.
Also, the new game starts after the previous game's main story ends, but before all the extra goodies takes it to 100%.
So, the most likely scenario is an overlap of ToN & TGO releases some time in the July/August timeframe, with ToN including all the bonus goodies finishing up in September. And if you want to take Evie's words at face value, ToN's main story is already over and so we might even get the start of TGO in the 2nd half of June.
Ah! I only play LU after complete so assume "Bonus Content" add after 100% completion. I think Treasure of Nadia story far from over yet for Sofia not reveal how she not age although carry Tikpak curse for centuries (door in cave under mansion still lock) and Madalyn/Daemalius subplot not resolved (two door and rusty gate in church still locked). Madalyn also meet Genesis Order character Sister Judy in Treasure of Nadia and spirited away somewhere not yet revealed so must be several more chapter of Treasure of Nadia to go to end game and give lead in to new game in which several ToN characters (Madalyn, Henry, Diana and Tasha) look set to appear, maybe briefly in cameo, more fully or in flashback perhaps, Madalyn certainly I say, as well as Genesis Order characters introduced early in Treasure of Nadia (Sister Judy and Duncan Helfer) who may have important role in Genesis Order (Sister Judy for sure).
Difficult to say when game will end under circumstances since not know what Evie content will be. If very brief like sex chamber thing in Lust Epidemic not much otherwise if longer mini-adventure involving Evie, maybe explaining her history and how got trapped in crystal etc., could be longer. Many loose end to tie yet in Treasure of Nadia which developer may or may not bother to deal with if too lazy, or too busy, or both.
I thought Lust Epidemic had better story and Treasure of Nadia better graphics. If NLT Media include riveting story and even greater graphics in Genesis Order next game will exceed all previous game by country mile IMHO. Am hope anyway and also for better and more capable MC not nasty rapey piece of work like Brad or enormous gormless twat like Henry.
