Whoops! Official Sony Ericsson press shot seems to leak W350 successor

Yo, Sony Ericsson, make sure all of your marketing folks are talking to one another, alright? Remember, communication is golden -- a simple email could've been all it took to avoid leaking a new, previously-unknown device through your own product shots. It seems that the press materials for the MS500 speaker contained this little gem, which is allegedly "Twiggy" -- the W350's eventual successor. That's all we know at this point, but the W350's over a year old now, so we can definitely buy that there's something in the works. Couldn't they have at least been bothered to take off the protective plastic thingies?
