No port, and I doubt there will be another Zelda on DS after Spirit Tracks, the GBC & GBA all had two Zelda's and two Zelda's only. DS doubtful will be different. Now, for the next DS a Four Swords would be good, I remember way back in 2006 (maybe 2005) their was talk of a port of Four Swords so the idea is there (presumably they abandoned it for Phantom Hourglass).
