Your just talking now as sakagucgi has stated that Blue dragon did what he wanted it t do in japan. http://www.gamespot.com/news/6167571.html?tag=topslot;title;1&om_act=convert&om_clk=topslot

" I was satisfied with the initial goal that we set for Blue Dragon, which was 100,000 units in Japan, but now it's on the road to sell through the 200,000-unit mark. So I'm highly satisfied with the sales, and it has proven to be one of the key platform drivers in the Japanese market. So I feel that our objective has been accomplished."

Lost odyssye performed similarly. Resonance of fate Selling 1/3 on the 360 isn't a sign that it should be dropped that sounds ridiculous if it sold 20k on the 360 then i would say it should have been dropped. Business wise it's smart for konami to put MGSV on the xbox one as well it is going to sell to people that would not have gotten a ps4 for it and they already have played MG hd collection on 360 so they are familiar with it theres plenty of different variables to this though. 

The tales remakes are not remakes of remakes thier just remakes. Also they added alot of new things like extra characters a modified battle system, new artes, new music, scenarios and cutscenes. Tales of innocence recieved good reviews and innocence R got slightly higher reviews. Tales of hearts got a 34/40 from famitsu which isn't to bad either. 

Also resonace of fate sold 900k which is around the norm for their games so i don't see how you see it as a failure and they never release sequels to games to close together. The Star Ocean games are spaced pretty far apart same goes for valkyire profile. 

The multiplat idea certainly has some merit - of the 7m sales of FFXIII, 2m were on X360. Now of course you could argue that PS3 exclusivity would have meant that that version sold more, but even still I think the extra sales were worth the cost of the extra dev time and the port. Admittedly however FFXIII-2 sold less than 1m on X360 compared to 2.4m on PS3, but I think for some games this is a viable option (although they may not need to bother if PS4 dominates in the west this gen).

All figures from here on Vgchartz

japdevs want handhelds and mobile.

thats it.

Why would they need sony?

In theory they would need Nintendo (if they would finally start to bring games to Nintendo main consoles) becaue WiiU is less powerful and people would not expect graphics better than PS3 etc. PS3 level graphics would be enough.

Japanese games are usually low budget when it comes to visuals and the PS4 is obviously alot more powerful than WiiU. Other than Final Fantasy that has massive budget most japanese companies would be wise to bring games to WiiU because there is less presure to deliver good graphics. (like the PSP vs DS in the past)

So japanese devs can only make profit on a Sony console?

Hah. There are a fair amount of JRPGs that did good on the western machine (though the fanbase were much smaller, I'll give you that).

EDIT: On top of that, Nintendo is also a viable option.

Aside from some bigger publishers (Sony; Square Enix; Capcom; SEGA), a large portion of Japanese PS3 games are still sporting PS2-era graphics (see: Tales of/Monster Hunter/Gundam/Earth Defence Force/Way of the Samurai/Atelier/Neptunia/Disgaea/Legend of Heroes etc.) despite the PS3 being capable of much better graphics (see: pretty much anything else).

I don't see why an upgrade to PS4 would make them change their mind and jump ship.  They didn't mind such a big gap this generation; I doubt they'll mind an even bigger gap next generation.  Maybe not having to mess around with the cell processor will actually make things easier for them.

If "suitability of graphics for the hardware it's running on" was the criteria, Wii would've received a hell of a lot more third party support than it got.

i'd say unlike japanese devs, japanese gamers never trusted microsoft. guess they learned now that focusing on an forein platform gets them nowhere down there.

You forgot Catherine, bad sales on xbox i guess because Persona 5 is only on PS3

Don't forget that PS3 was very difficult to develop for. This is what Sakaguchi said in a interview when asked about PS3:

"The machine's architecture is tricky, and I don't like Ken Kutaragi."

And now Kaz Hirai:

"We don't provide the 'easy to program for' console that (developers) want, because 'easy to program for' means that anybody will be able to take advantage of pretty much what the hardware can do, so then the question is, what do you do for the rest of the nine-and-a-half years?"

By that mentality, Final Fantasy 7 would have sold twice as well if Square just stuck with Nintendo, since that's where the fanbase was....
