Pokemon, DQ and Inazuma are no better as a JRPG barometer : they go well beyond the standard JRPG audience, you know that as well as I do.
I must say you're quite wrong on PS3 JRPGs. EoE stands at 240K, which is really not that bad (52th best selling game of the year). Totori is at 138K and still selling 2-3K a week whereas Rorona stopped at nearly 80K. Tales of Graces F is at 306K and still selling 10K when Vesperia stalled at 350K (which is the 3rd best score of this gen). Even niche JRPGs like Neptune make the headlines and make it to the West (which, sadly, is not yet the case for most Wii JRPGs).
We'll see what future holds for DQX and VersusXIII (hopefullly on Jan. 18th, the wait is killing me) and I keep faith on 3DS because I will probably get it, just for Tales of the Abyss and Professor Layton vs Ace Attorney!
