I have never felt that JRPGs were outdated, but I have felt that they aren't making good ones anymore. I haven't played a JRPG that I consider truly excellent this decade.

And the notion that JRPGs are all turn based is absolute garbage. Looking at me current gen video game shelf I see: Disgaea 3, Eternal Sonata, Final Fantasy 13, White Knight Chronicles, Lost Odyssey, Infinite Undiscovery, Last Remnant, FF7: Crisis Core.
Over 50% of those are some variety of real time.

IMO JRPGs need to do away with the idea that they have to be real time and fast. I have yet to enjoy one of these systems as much as a more traditional turn based one. It isn't the slow turn based systems that give JRPGs a bad name, it is boring turn based systems that give them bad names, replacing it with a mediocre 'real time' system isn't any progress forward. Especially when they then have to make my other party members AI, completely removing the ability for any highly detailed encounters. (Though I don't often praise FF12, giving the ability to modify your AI is a gigantic step forward)

Is a JRPG going to be a mega-hit in North America nowadays? No, I highly doubt that they can make anything to go up against Halo or CoD. But their attempts to make the games 'faster' aren't going compete either. They should just focus on keeping their existing fanbase happy.
