Hi, I found some info about X's tour at BARKS, japanese music portal site.
http://www.barks.jp/news/?id=1000044531It says,
1 The tickets for Paris will go on sale at 10th November at 10:00 am.
2 X JAPAN's management was negotiating with promoters, it was concluded almost.
Live Nation or AEG will promote X JAPAN's world tour.
Live Nation had promoted the concerts of Madonna, U2, Micheal Jackson, and so on.
AEG is also big promoter. And the cost of this tour is about 10 billion yen.
3 The title of this tour is FINAL~to end our pain~.
SO, I think the officila will put on information soon.
