Zazillo,
Conduct a search on this forum as well as on Flightinfo.com for a guy called Typhoonpilot. He is a furloughed USAirways pilot who now flies for Emirates - he can give you the scoop. At the end of the day, never trust anything Emirates says - they can change the terms they give you at will. Dubai is a great place, but I would be concerned about permanently resigning from NWA.
I know that Jet Blue and Air Tran are hiring in the States - I suggest you actively apply to those carriers as well... Good luck - and contact Typhoonpilot using the Search function (I've seen him on Flightinfo.com quite a bit too).
