MacPlus.org is reporting that one marketing report floating around Apple proposes the possibility of revamping of its product line with the introduction of a low-end G4 "box" with 32MB VRAM, and 256MB RAM. Target price is reportedly $599.
Such a target price is said to be realistic, and comes with expectations of significant sales gains in consumer and small/home office markets. Impact on Pro-machines is projected to be minimal, and with only 8-12% reduction of iMac sales.
If true, this might fill in a much-requested segment of the Mac product line -- low end "headless" machine. It's unclear from this report if the machine would be expandable.

Addendum: MacWhispers seems to think this is unlikely due to lower costs of the 970.
