In game that have more than 1 possible ending i always try to explore all of it to know the outcome of each ending/epilogue. I think we can all agree they already know that ending naruto with NH [and SS] and aiming it to the west abandoning their own country because they think it will bring more money is a bad idea, in the end it did not meet what they expect. There is no reason for them to not try NS ending. I haven't heard or read anything new about this new era project since boruto movie air in theater, Maybe they are in deadlock discussion/debate. If you were the SP staff what will you do? let the anime continue with like the manga with NH ending keep wasting money already knowing that the west did not bring that much money and close the book let the franchise died?? or you try to end the anime with another ending to see the difference??
Even if they end the anime with NS or other ending except NH/SS naruto is dying/death franchise anyway, why don't try something new something different maybe miracle happen and money will come, who knows.
Well if I took over I would have them come out and say how the ending is not that good and that Naruto became a scumbag and that the last and Boruto are no longer canon films make chapter 700 none canon either and just keep saying sorry that the ending they thought was good was not what they thought after that do the NS ending and call out Kishi BS as well.
