The new generation is upon us, and it seems plausible that the days of big-budget JRPGs may be drawing to a close.
There was a time when Japanese developers put a ton of money and resources into their role-playing games; Final Fantasy isn't the only example. Squaresoft and other devs really produced some seriously eye-catching games with ridiculously high production values. There were still a few niche titles out there but moving forward, I'm afraid that's all we'll see. Things have drastically changed.
The JRPG will likely continue to survive and perhaps even flourish with that select group of gamers who still adore the genre. But as no JRPG will likely be considered "mainstream" ever again, the amount of time, energy and overall resources will be reflected in that demotion. Some will argue that Final Fantasy XV is a JRPG and it has a plenty big budget but personally, I argue that it doesn't even qualify as role-playing. Maybe it will and I'll bite my tongue but for the time being, I just see a flashy action game with a few RPG elements. Hell, most action games have those features these days.
The JRPG will exist mostly in the digital downloadable realm in the new generation, and it may also enjoy a resurgence on portable devices as well. But as far as big-budget AAA productions for consoles, I think it's over.
