Well to be fair, Level-5 makes a lot of their titles either with Square Enix's money (when they did Dragon Quest) or with Sony's money subsidizing exclusives, but I would consider them a major studio. They helmed the premier Japanese franchise for some time.

In any case, I'm not saying "big studios" make innovative JRPGs, or that there have been many of them. Just that Kotoroa made an overly pessimistic statement that was pretty easily discredited.
