I suppose the 'huge' announcement could relate to either Star Alliance or Skyteam. I am sure that I read somewhere a while back that DJ was expecting to make an alliance decision in late 2012. I guess by then they should have had enough time to work out which relationship is more important to them, the Tasman one with NZ or the US one with DL.
Then again, it might be absolutely nothing, crew rumours are notoriously unreliable, and I don't know that an FO is going to already have a heads up on major developments
