I think part of it is that there just aren't as many console JRPGs as there were in previous generations. We're 4 or 5 years into this generation, depending on your console, and the JRPG pickings have been slim, and for the most part, mediocre. There just really isn't a lot to choose from.
There hasn't been a SMT game on this generation of consoles, but there are like 7 games in the SMT line for the PS2.
Square Enix probably released something like 30 JRPGs on the PS2, but have released like 5 this generation in 5 years.
Level 5 has released one JRPG this generation, and released 4 on the PS2.
There were 5 Tales games on the PS2, and 3 released this generation in 5 years.
I'm sure that if you look at other JRPG developers, you'd see similar stories. I'm not all that familiar with JRPGs and JRPG developers, so maybe someone else can add.
At these rates, this generation will have to last 15+ years to develop the same kind of JRPG library that the previous generation had.
