The RPG market is fine, especially on Sony consoles or PC's. The problem isn't that there aren't that many RPGs, but that just about every other sort of game gets more marketing and media attention, particularly in the West. Witcher comes to mind in particular as a series which didn't get a lot of marketing.
In fact, I'm hard pressed to remember an internet ad campaign for an RPG for a VERY long time. I remember Halo, Injustice, Splinter Cell, Saints Row...but not any RPGs. The market itself is pretty healthy, but you'd not know that because there are almost no advertisements for them compared to other genres.
