Iron Man bad guys to return in Iron Man 3

According to Latino Reviews, the terrorists who had been assigned to murder the Genius, Billionaire... (you know the rest) Tony Stark, are going to make an appearance in Iron Man's next appearance: Iron Man 3.
Latino Review released a photo of a crew members hat, showing the symbol of 'The Ten Rings'. Many believe that The Ten Rings have been hanging around in the background of the Iron Man movies. One of these indications was in Iron Man 2, where Whiplash (Mickey Rourke) is given false i.d to get into the US of A.

In the comics, The Ten Rings are in fact actual rings, but The Mandarin's rings! The Mandarin is set to appear in Iron Man 3 being played by Ben Kingsley. 

So could the Ten Rings be a big part of the story?
