Personally I can't wait until next year when I'm, planning to go to Osaka. Of course, that is right next door to Kyoto.
I'm going to spend a week in Osaka then travel by bullet train back to Tokyo. I want to spend more time in Akihabara. I also want to check out Harajuku and several other sites I didn't get to check out on my last trip. Among those are:
Studio Ghibli Museum:

Edo Wonderland:

Takenaka Carpentry Museum (in Kobe):
