SCSI-3 has not been released so where did they get SCSI-5?

The standards are:

SCSI-1				5MB/s
Fast SCSI (aka SCSI-2)		10MB/s
Fast Wide SCSI			20MB/s
Ultra SCSI			20MB/s
Wide Ultra SCSI			40MB/s
Ultra2 SCSI			40MB/s
Wide Ultra2 SCSI		80MB/s

See http://www.scsita.org/terms.html

Yes - SCSI cables can get expensive for decent quality.
