Yup, the only thing the bug fixes did was properly add the Kirito Route scenes and the right Inoda Blog entries for it, if you don't want to replay it then there is no need and can you read them around here. I just did it 'cause I had the time and am interested in it, but given you gotta start even before to see all the new bits most won't consider it worth it.
Realistically, yes, but also no: The only way Inoda is getting Suguha or Sinon with how close the game is to ending is with the council's magical brainwashing, and for that to happen they have to actually defeat the council, so even if it did then it won't be until the very end of the game most likely.
Clarifying more on what Uwuktz said: You don't HAVE to reject all the girls, in fact you can watch all their scenes and still stay in the NTR/Inoda route (And funnily enough, as of the last update, if you don't have enough pruience/perversion gotten from said scenes anyway, you can't peek at a scene of Liz getting sexually tortured by Inoda, LOL, so seeing them all is actually the recommended choice, you just gotta avoid the 2 options that 'awaken' the Dark side of Kirito during the 17th of the last month, which is calling Alice or accepting Liz's advances). And for the Bad Ending branch, assuming it stays, you actually need to reach 80 anxiety during the events of the 18th of the latest month before going to the cowshed at night or the 'date' to unlock it won't happen period (Also, is Asuna who forgets her phone, and you still gotta go inside alone to go to the Bad Ending route, but you also can choose in to go together to stay in the normal Inoda Route if you want to).
