Unfortunately I don't have any detailed information, but I heard today from one of my wonderful reps that Cadbury will be putting out a new bar later this year or early next year that is supposedly similar to a Twix (which is owned by Mars). A Twix is a bar (pair of fingers) made of milk chocolate, biscuit and caramel, so it could be interesting to see what Cadbury does with that.
Cadbury also owns The Natural Confectionery Company, and there are two (count 'em, two!) new TNCC gummy varieties due out later this year. This one I don't know any more about, but I will keep on twisting the arm of my Cadbury rep for more gossip as soon as it comes out, I promise!
