Quotes from Okubo:

And then just to remind people that Bandai Namco published this:

All in all this idea that SC6 didn't meet expectations or that it failed is bollocks. It was a sales success for Bandai Namco. Sure, the publisher would love to have sold way more, but that's literally the story of every publisher. Not every game has to be a AAA sales success, a lot of IP's simply have a small but core consumer base and there's nothing wrong with it. This idea that Soul Calibur is going to be standing side by side with the sales giants of Tekken/Street Fighter/Mortal Kombat is delusional. It is a mentality that the Calibur community cannot break away from.
There's more to this than what I'm letting on, but there's no point me mentioning the details as it boils down to a "trust my source bro" and a Twitter post so far down the eather by the director Yoshinori Takahashi publicly saying that he wishes to continue working on future Calibur entries. I haven't been on Twitter for years so I have no idea if here's still working there, but I haven't seen anyone here chirp about his departure from Project Soul.

Soulcalibur 5 and Its DLC Will Be Delisted Soon - PlayStation LifeStyle
It's the end of the road for Soulcalibur 5 and its DLC as Bandai Namco has announced that it's pulling both from online storefronts.
Bandai Namco said back in 2019 that it considers Soulcalibur 6’s launch to be “successful.”

SoulCalibur VI Could Be the Last SoulCalibur if the Game Isn't Successful
SoulCalibur VI's Producer explains that the SoulCalibur franchise risked disappearing, and the success of the upcoming game might be critical to its survival.
"The first thing is that the IP itself of the SoulCalibur franchise had low expectations from the company. It was actually facing a crisis of maybe disappearing. It took time for me to convince the company."
"We don't want to blackmail the users by saying that it could be the last one, but as it is, yes."
"Since the SoulCalibur brand is facing a crisis, we have nothing to lose, so we just decided to do what we want to do."
