Hey, hey.
It's not incompetence. As it stands, things are great for SCE. Game is in development, and it's coming to PS4. Securing a big game isn't that simple. Square Enix also has to take a look at a lot of things, and what makes sense for them at the end of the day, is what's most sensible. Considering how far we are, and the nature of these things, we can amend things in the future, if it makes sense. But regardless of any of that, SCE is going to benefit the most from this game. FF is a Playstation franchise. SCE will get behind this in a huge way, and the marketing campaign for it will be big too. Regardless of whatever ends up being the most sensible option, SCE has already benefitted the most.
Securing big games takes a lot of cash, and simply doing it to appease fans for something as silly as "bragging rights" would be pretty stupid. Depending on what's involved, that support could be provided to bring another game from somewhere. Regardless of any of that, it's coming to PS4 first. That much can be assured. Beyond that, it's mostly SE's decision. But people shouldn't buy too much into the whole it has to be on PS4 only or whatever, in case they end up being disappointed in the future, as if it's some kind of personal offence.
SCE is really happy with things as they are. I see no reason why others need to be upset about it.
