New bottle pending from Coke?

Coke is already test-marketing aluminum bottles, (see what they look like here) but Coke also has a different aluminum bottle design (shown at right) listed at the United States Patent and Trademark Office. The trademark, filed in July of 2005, specifies the silver bottle and white text – a color combination that isn’t present in any of the test-marketed bottles.

Does anyone know anything about this?
