I listened to a replay via nwa.com of Richard Anderson's (NWA CEO) presentation at Goldman Sachs Conference, and he said that NWA is aiming for a mid 2004 entry into skyteam. In the pdf available for download it says that it is targeting just a 2004 entry, nothing more specific.

last line on page 19 it states the skyteam entry target.
