Could Apple go back to SCSI ?

Apple long appeared as a pionneer using the SCSI when all PCs would use a very slow IDE.
Obvious economical issues as well as the rising performances of the ATA, made them go back to a more common policy.
Everyone thought the Serial ATA would eventually kill the SCSI. This appears to be wrong.
Soon the SCSI norm will go from parallel to serial, thus becoming Serial Attached SCSI. Its theoretical maximum output would be of 3 Gbits/s at first, then 6, and would allow a chain a 128 HDs.
Its fantastic advantage is that it would be possible to plug on a SCSITA bus a SATA HD, this will work flawlessly (without taking advantage of course of the SCSI ability, that is less CPU sollicitation). The choice would be between installing less expensive drives, or some with very high performances (at a cost), and mising the two will be possible as well.
The unique ability of housing 15000 T/mn HDs in a RAID Xserve would be quite a commercial motto for Apple. But is the brand still motivated enough to initiate elitist technological choices, for something else than CPUs ?
