If Nintendo consoles would have been THE home of JRPG, then I would have bought them, which I didn't.
I think that both Nintendo and Sony, in their respective consoles and handhelds, are strong hosts to the genere, it just depends what kind of JRPGs you love. Then, there's the lack of translated editions for the western market, who further gives an untrue overview of the market.
For example, I went for the PSP, instead, and got Last Ranker, Senritsu no Stratus, Final Fantasy Type 0, the remake of Persona 3, Fate/Extra, two Valyria Chronicles, Y's Seven, and many others... Each one of them appeals to me much more than any Dragon Quest or Pokemon. And it's of no interest to me if, thanks to underage consumers, Pokemon sells millions while Last Ranker sells a little over one hundred thousands; I care for JPRGs that are fun to play for me, and those run mostly on Sony systems. And yet, for non Japanese speakers, most of those games are, basically, non-existent, as they were never translated, and never will.
But please, don't say that Nintendo is the environment where JRPGs thrived, because this is a very imprecise and uninformed statement.
