I'm going to Berlin too!
Anyone going to the Berlin show who has not purchased tickets! They are available a little cheaper from the NeoTokyo store - http://www.neotokyo.de/
(31.90 Euro instead of 33.55 Euro)
My girlfriend (TheKueken) personally confirmed this with the NeoTokyo staff. Tickets will also be on sale at their physical store in Berlin and should arrive sometime next week. (The tickets are being printed now) They ask that you call before coming over to purchase them, though, as they may not have arrived yet.
Do the Berlin folks want to arrange some sort of meet-up? Kue and I are planning on stalking out some of the tourist areas on Saturday and Sunday pre-concert. We figure that Yossy and Rika will do some sightseeing before the show since they go to Finland the next day. I'm leaving on Monday, so I'd prefer the meetup be before then
