No recent news on oneworld's website - this is the most complete news item, but it merely says "in 2007," and there is no further specificity as to date I can find. It DOES say, in another bit:

"March 1, 2007

oneworld® today confirmed the dates when LAN Argentina and LAN Ecuador will join the global alliance as affiliate members.

Both airlines will board on 1 April, when Japan Airlines (JAL), Malév Hungarian Airlines and Royal Jordanian Airlines will also start offering the alliances services and benefits as full members. Five other members of the JAL Group will also join oneworld on the same day, as affiliates -JALways, Japan Asia Airways, JAL Express, J-AIR and Japan Transocean Air.

Dragonair, which has also been elected on board the grouping as an affiliate member, will follow later this year, after all necessary joining technicalities and processes have been completed.

As affiliate members, LAN Argentina, LAN Ecuador and Dragonair will offer the full range of oneworld services and benefits."
