I especically like the statement:
"Our tiny antenna can be placed in the car or cast in metal, and is at least
as good"

Great, an antenna working even if cast in metal....

Time will tell.

It's likely we'll not find out the exact details (if it lives upto ad-bumk that
is) but what else can it but a coil wound round a lump of ferrite ?

I don;t personally see why a ferrite can be used for transmitting - but then I'd
need filling in as to what the technical reasons are for this supposed reasoning
is.
