8 years since this was announced, and you'd call this "early"?
I think it's absolutely crystal clear that Versus/XV is beset by the exact same production flaws that led to XIII taking so long and critically under-performing. No, based on the time it's taken, it is actually showing worse symptoms of development hell.
The question is whether the game will have spent long in this sluggish oven to come out a good game anyway.
And I do think we have plenty of precedence to look at a demo and not think "this means its a slice of a bigger game that is around the corner" but rather "this might be a mere milestone in development, and could certainly be one of the first pieces of the game that they actually complete in full".
