As you know, there will be the first IEM5 event at Gamescom in Koln, from August 18th to 22nd. According to ESL admin there will be quake live matches every day.
My girlfriend and I plan to come for the full event. Afaik Koln is a very nice city, and given the summer time this should be a much more pleasant stay than in Hannover, likely allowing for a better ESR meet up. So if you plan to come, please post here.
