There seems to be some organisatorial changes being made to some of the EU dates at the moment. Presales for Barcelona were postponed to a later date without any notice and presales for Zurich and Lisbon were changed from February 7 to TBC (To Be Confirmed). On top of that, the UK Ticketmaster site no longer seems to mention a June 18 Twickenham date at all, only the June 19th date is mentioned.

We have no idea what’s going on, so I’m afraid we can’t help you there, but perhaps the people at U2.com know more (hint, hint, inform subscribers, hint, wake up boys)
