No decent RPGs in the last few years? I'm pretty sure every platform has had their slice of good RPGs.
The DS is overloaded with them (mainly JRPGs, but I think that's what is preferred here), Xbox 360 has been on a binge with them, the Wii has a handful. I think the only platforms that could be described as struggling for them would be Sony's, but that's mainly due to the fact they get re-releases or ports.
I think it's just a change of tastes, my preferred genre is far and away the RPG genre, but I haven't played one yet this year.
I have a number of RPGs in my collection (I won't list so as not to come across as boasting) that I haven't even touched. I know I want them, but I can't bring myself to play them. It's not a "relaxing" genre for want of a better description, and I've just wanted brainless fun like Banjo Kazooie and CoD4 recently.
