Interesting read so far this thread.
Yes, SquEnix are a business. We all get that, they want money and they go where the money is. In the case of many recent games this money is from M$ directly I'm sure as it sure hell isn't the JRPGs on the 360 sell well, UI is selling great isn't it? Especially in Europe. :P
People can stop with the whole attach rates crap. If the games came out on the Wii they'd sell better, we all know this, especially in Japan. PS3 has more consoles in Japan and that's where this matters surely. A console with a million more units is not getting the games while one with less is. Attach rates or not, you have a better chance of making money on a console that has sold 2million with an attached rate of 15% then one with 1million and 25%. (not accurate figures obviously)
In the world markets, JRPGs are not the sellers they are in Japan and where they matter the 360 is still the weakest selling console.
Luckily though, SquEnix love handheld consoles and are giving both DS and PSP a nice load of games.
