Real Soon Now adv.
[orig. from SF's fanzine community,
popularized by Jerry Pournelle's column in "BYTE"] 1. Supposed
to be available (or fixed, or cheap, or whatever) real soon now
according to somebody, but the speaker is quite skeptical. 2. When
one's gods, fates, or other time commitments permit one to get to
it (in other words, don't hold your breath). Often abbreviated
RSN. Compare copious free time.
