I'm sure it is, but for pretty much decades now, Namco has had a pretty successful model with the following pattern: lead development for their 3D fighters on a new piece of hardware with their flagship fighter property, Tekken, dumping money and talent in to the process to overcome the learning/development curve; drop said Tekken game a decent bit of time into that new generation; once the Tekken project is released and selling well, reconstitute Project Soul (remember, it is an ad-hoc team they put together for each game in the series, not a standing internal studio) by porting over key development personnel and the experience they garnered for the new consoles through development on the Tekken title, allowing for a decent game to be built on a more modest and predictable budget.
Now, just because it has been done this way for a long time doesn't mean the model can't change--indeed, the changeover to the continuing support model of development has clearly stretched out and finessed the particulars of these timelines a bit. But I'd say Namco probably view this as a "if it's not broken, don't fix it" kind of situation. So, considering this cycle, and increasing development times in the industry in general, and the drop date of SCVI, I think Sytus is probably right on the money here, or close to it: I think you are looking at 4 years minimum here before we see SCVII.
That's never going to happen, and you really shouldn't want it to: being one of the more unique customization features of any fighter, it helps ship units and justifies a larger budget than SC titles would ever otherwise receive in the current circumstances. Wishing it away would be cutting off your nose to spite your face: who cares if other players receive a feature you don't like, if the result is a bigger game for everyone, including enhanced budget and features for aspects you do care about? Although, from context, I gather maybe what you were trying to say is that you just don't want them in online multiplayer? If so, meh: I don't need them there, but I find the complaints about the impact they have on competitive play exaggerated to say the least. But if they were removed from ranked, I wouldn't shed tears.
