This has been one of the strangest on/off announcements I've ever seen so I wouldn't take it as a given until tomorrow...
Run-up to Christmas: European Tour announce they will be taking the Irish Open back to Dublin area. Rumours centre around Killeen Castle, Carton House and Portmarnock. Nothing official announced
December 20th: All news stories report that Carton House will be the venue with official announcement later that day. Announcement never comes
January 5th: European Tour set to make an announcement on January 6th from Portrush... Seeing as Portrush was scheduled for 2013, this could possibly just be the venue for an announcement for the next 2 years?... Maybe?... Either way, the news stories were wrong before Christmas so I'd wait for final confirmation tomorrow...
