I've heard both too, but I've seen docs that refer to the "NextSTEP/Sun" namespace .. somewhere buried deep in the Apple docs .. but I can't find it now. Either way, both "NextSTEP" and "NextSTEP/SUN" have been used to answer this question in the past, so I'd say both are correct .. especially since Sun left the project early.
