I've no interest in these at all but thought I needed to post something here for the sake of those that are interested. In the Canadian packaged (=trilogo) basic figures (3 3/4") there is an insert showing lots of the coming toys. For the most part, nothing that hasn't been seen before, but part of the pictured stuff is in the Attacktix line.
They show pictures of the starter set shown below, though not the identical shot. They also indicate it comes with 1 secret figure. I've not seen that elsewhere, though I could have easily missed it. They show a silhouette of the figure, but I don't have a scanner handy, so can't get the image for you.
