Maybe you should about what kind of game Japanese developers put the money in the last generations.
Mostly all of them are Middle-term games (not AAA, not short budget) and the industry in that time or even this generation doesn't allow to be promoted as an interesting or relevant game.
With the industry demanding AAA games every quarter or month, a developer needs to release 3 or 4 AAA multiplatform games every year and only a few of them do that, mostly Western devs.
Nor Sega, nor Capcom, nor Konami, nor Square-Enix, nor even friggin Bamco with all their money can put all those conditions.
With the economic recesion in Japan as an icing in the cake, it's obvious why many jp devs and enterprises now are starting to move forward in the mobile business and only put their most relevant IP's in consoles.
At least Sega has done this years before and now they are in a good position.
