I can see that, although in this case we've to look from a broader perspective.
- We haven't seen that many new franchises funded or published Nintendo in the past 10 years: Splatoon, Xenoblade, and few others (smaller than these), it's always refreshing when they do this.
- It's rare to hear they want to build a franchise out of this, usually Platinum Games titles are one and done like those you mentioned.
- eShop doesn't have that many games in this genre, and they're not going to get many from other studios, so for variety sake, any game from Platinum is important.
We still don't know much of the story, but the premise is really cool, very reminiscent of Psycho-Pass.
Beyond the combat though and the innovation brought there, the investigation is also interesting, similar to L.A. Noire: find secrets, catch liars by interviewing them.
