It's my understanding that the London stops were the only two dates Hikki has planned for Europe at the moment. There's nothing to say she won't return there later, and I could be wrong, but as I said, that's my understanding.

Sorry. It must really stink for you to have missed her. I came very close to not seeing her in LA and it threw me into a very gloomy state- not sure what would have happened if I hadn't been able to go. I'd probably be calling for group therapy sessions with all the other Hikki fans that missed their chance. xD

Anyway, I feel for you, and keep in mind, there's always hope! It's my opinion that she'll have at least one world tour before she retires, just to go out with a bang, so even if you have to wait a couple of years or so I'm certain she'll be back in one capacity or another. :3
