Sony Ericsson Spiderman 3 phones also in Belgium

Looks like Sony Ericsson isn't only promoting the Spiderman 3 phones in Hong Kong and Taiwan. I found these pics over at planete-se, a French site. The pics are originally from a Belgian site, dandu.be. They seem to be a poster ad but no info was given. I am guessing an ad at bus stops? Here, the phones in the campaign are the K320i and Z530i unlike the higher end phones being promoted in Asia. These phone come with an actual Spidey 3 designed housing and not a specially designed crystal case. I can't wait to see the movie.
