Poor old Oneworld out in the cold alone

In many’s opinion, the worlds REAL alliance of airlines, Oneworld seems to be somewhat isolated in terms of growth prospects. While Skyteam gets KLM, Aeroflot, South African and possibly CO and Northwest, Star gets LOT Polish and US Airways, whats left for oneworld?. Bankrupt airline Swiss will soon join but the alliance will be small compared to the likes of Skyteam. Although it has American, only $50 Billion is its revenue, compared with a 2012-forecast of $95 Billion for Skyteam Alliance as Oneworld actually declines.

Which airline is lightly to join Oneworld?

I say JAT Airlines is a possiblity.
