If not.... can you convert one to the other more easily..... I mean if you put a Raymarine masthead Wind inst and then fitted some other NMEA 2000 sytem could you use the Raymarine wind info, or conversely if you mounted NMEA 2000 Masthead, could you convert that info to SEATALK if you decided to go RAYMARINE..... or shoudl I just put BOTH cables in the mast???

You really can't go wrong by pre wiring your mast with an NMEA 2000 drop cable. If you decide to use RayMarine instruments, there are adaptors. And a RayMarine cable would be MUCH more expensive. (And yes, a Nk2 cable and a SeaTalk spur cable are identical on the inside)

That being said, I would ***NOT*** prewire my mast because often the wind transducers come with the wire you need!!!! So just buy the transducer and be done with it.
