Let's take a look at network and disk technologies.
First, disk technologies have been increasing in speed at 2x intervals. First there was plain SCSI (~10MB/s). Then scsi 2(~20MB/s). Then fast SCSI (~40MB/s). The Ultra SCSI (~80MB/s), now Ultra SCSI 3 (~160MB/s). (I might have misplaced the names of the scsi technologies, but the idea is the same).
Also, let's look at FibreChannel. There was FC-25 (25MB/s), then FC-50 (no commerial organization used this, but it was 50MB/s), and currently, FC-100 is the dominant technology.
Again, 2x intervals.
Now let's look at ethernet. It's jumping at 10x intervals. 1Mb/s, 10Mb/s(Ethernet), 100Mb/s(FastEthernet), 1Gb/s (Gigabit, which incendentally is theoretically faster than FibreChannel... 125MB/s), and 10Gb/s is on the
way.
So by taking historical scaling into account, ethernet dead? Yeah right. Now that's not to say
that you'll actually ever realize the full bandwidth of any of these technologies. You still have mechanical parts in these drives. Caching and I/O randomness can either help or hurt your performance.

I caught Access Hollywood on TV today. They stated that Lucas had a change of heart. Tickets will be available before opening day.
