Let's hope the codeshares will happen but the announcement seems to have been delayed if the article in the Business Traveller (based on an interview with the airline's marketing director) dated 7 February this year is accurate. The relevant bit of the article is this.

A formal announcement on this will come in the next couple of weeks.
