We know White Knight Chronicles is getting an innovative battle system. Shin Megami Tensei games are also very different from other JRPGs

I fear change, and I prefer things stay the same, as much as possible.

yes, especially the EBA resemblance in Sonic Chronicles

RPGs would eventually get very boring if they stayed the same.  Look at FPSs, I only play the best of the best because most use the same mechanics that have been used since Halo.

Most changes in Japanese RPGs will need to do with either moving away from a turn-based battle system or the improvement/change in the method of storytelling.

I found Persona 3 to be quite innovative. But I must admit it did eventually go to the "save the world" kinda story.

Innovation isn't always a good thing. Secret of Evermore is different from everything I have played (save for the gameplay being almost a secret of mana copy). The game isn't that fun. Dragon Quest 8 is as generic as a game can get and one of the best I have played. Chrono Trigger didnt do anything new and is the best RPG I have ever played. CT even removed some of the annoying and pointless features every RPG must have nowadays.
Innovation is just a fancy name if you can't make your game more enjoyable.

Personally I don't want to see much change, maybe just refining of storytelling and character development. I'm already pissed that there aren't as many turn based RPGs being made anymore, and I live in constant fear that RPGs will all become like TWEWY. (no offence if anybody likes this game, I'm just stating opinion)

innovation is overrated, i tend to yearn for greatness.

YES!!!!  Finally someone else who comes out to say that innovation means diddly-squat.  All I care about is how fun the game is.
