And you're getting all this information from.... where?
PlatinumGames: They stated in an interview with PC Gamer Magazine that they want to put as many of their games on PC as humanly possible. Since that interview, their main focus has been console-only game releases with products like Wonderful 101, Babylon's Fall and SolCresta coming off to me as them "testing the waters" for PC gaming despite having previously released Metal Gear Rising and NieR Automata
Bandai Namco Studios, Inc.: We complained about Ace Combat 7 and Code Vein when those games were new. Considering that we still insist on finding reasons to complain about Ace Combat 7 almost 3 years after its release, I think one can see why they wouldn't release Gundam Extreme VS MAXI BOOST ON to PC. And i dunno if a company that's willing to take a "PC gamers are too whiny to have (product name)" approach to selling their products can be trusted with making a smart business decision moving on from THE IDOLM@STER: Starlit Season's region locking on Steam.
Capcom: Yes, i am aware of their previous statement about them wanting to focus on PC some time ago, though the fact that DMC5 Special Edition seems like a return to the anti-piracy measures used on Street Fighter 4 and Resident Evil 5 makes that pro-PC gaming statement a very strong case of "I'll believe it when I see it"
And finally,
ATLUS can speak for themselves if their release patterns since P4G are indicative of anything.
I think the examples I mentioned should speak for how superstitious Japanese developers are about putting their games on PC. I think you can see why i prefer the idea of a multimillion dollar corporation making the big decisions about PC gaming for Japanese game developers rather than having those same developers make those decisions by themselves.
