In IAEI magazine's "UL Question Corner"(May-June 2006 issue), there's a 1/2 page Q&A describing the new MC Cable. (For some reason the page is marked January-February).
Southwire, the manufacturer of the new type cable,has a full page ad for their new cable in the same issue.
I'm sure it's purely coincidence

MC has an insulated EGC whereas AC doesn't, and MC is made from AL whereas AC is steel.
Both AC and MC Cable are available with aluminum or steel armor, and both can have an insulated grounding conductor.
The new stuff, as well as a whole slew of other information is available at
