The reality is that all 3 alliances are chasing the 3 major players (9W, AI/IC and KF).
9W has been closer to SkyTeam airlines, and AI have had a relationship with LH - so that leaves OW and KF :-)
The reality is that while AI/IC might just resume negotations with Star once the merger is complete, 9W is in hurry to get into any alliance just yet.
