I could swear I saw something the other day where Tabata came right out and said there's no plans to release on PC at this time.
Because they want double-dippers.
I can appreciate the skepticism, and I'll fully agree that personally I think Steam/PC is a really healthy platform for additional RoI but consider the situation here:
- The game is releasing in 2016 no matter what
- Luminous is an in-house engine*, significantly being built alongside FFXV
- Optimizing performance on consoles to hit their render target of 1080/30 is already going to be a long, tedious, iterative process on its own
- PC as a consumer platform, with its multitude of configurations and unforseen issues is very, very different from PC as a base development platform, which is a far more controlled situation. Tabata said as much
When they say "there's no current plans for a PC release, focusing on console versions", I think I can take that at face value, at least until the console version is out and is as good as it can be.
Additionally, (and I'm speaking in general, not specifically w.r.t. Square Enix) there's a whole dynamic of skepticism regarding PC cannibalizing sales, both in direct legit platform-vs-platform competition and the perceived ease of piracy, that's still front and center in a lot of business decisions as far as Japanese game development goes. Some companies are beginning to break the mold like Bamco with Zestiria, but it's still a significant factor in these things.
