http://www.taiwannews.com.tw/etn/news_content.php?id=742573 Just heard it on ESPN Sports Center as well, if the above link seems a bit dodgy. First tournament is in 2011 with two games in Feb and four in May, to be played in Dublin.
So the games will be played at the new Landsdowne road. I think each game should be played at their home stadium. I hope this true, I would love to watch these matches.
The first tournament will be played in Dublin. Or at least in Ireland. Subsequent tournaments will rotate between the four countries.
