New Sonic Screwdriver For The Eleventh Doctor

As well as a new design on the TARDIS, these pictures show the Eleventh Doctor with a new Sonic Screwdriver. We know from Forest of the Dead that the Doctor gives River Song a Sonic Screwdriver in the future with 'Red Settings' and 'Dampers' but this one doesn't look as though it has these on. Could this just be a new design on the Sonic Screwdriver?
