Sure, but they still dropped characters even after the game was rebranded to FFXV. From the background image of EoFF alone, which is a promotional image released as part of the E3 2013 press kit (so not even that long ago), 3 of the 4 characters aren't even in the game at all and the 1 of that is barely features for more than a few minutes screentime and a a few lines of dialogue. I can get behind the logic for stuff from 5+ years ago that was dropped, but stuff as recent as 3 years ago shows there was a pretty big shift, pretty recently, and it all coincides with when Tabata and the Type-0 team took over the project full time. We know from interviews with Nomura and Tabata that Versus XIII was around 25% done before it was rebranded to FFXV and targetted for PS4/Xone instead of PS3. 25% is pretty past the concept stage.
As dubious as the GameFAQs post is, it's pretty obvious that the game went through some big changes as a result of the change of director and outsourcing of some elements so there may be some truth (again especially taking the NeoGAF post into account too) in some of the rumours. After they already wasted time and resources on getting a project to 25% over 7 years, it's not beyond the realms of possibility that time and resources were spent cutting the scale down and re-writing/re-working to make the scope more manageable.
Either way, we'll probably never know so... ¯\_(ツ)_/¯
Again, as I said in another thread, I don't necessarily think Nomura's version would've been any better, and I thoroughly enjoyed what we got.
Yeah, the post-game stuff is fantastic. Probably the best offering in a main-numbered title in quite some time. (SPOILER)I would've loved to have had optional fights with Cerberus, Ultros or Diamond Weapon from Kingsglaive though.
