I work at a Sears and they just put like Blu-Ray previews on their preview loop that all the tvs play. Some of the titles haven't been announced with release dates either, like X-men 2 and Lawrence of Arabia had scenes shown. They did also a DVD to Blu preview too. Where they showed a shot from Kingdom of heaven with dvd on the left side and Blu on the right. It was pretty cool.
Showed some of the cool looking interactives for X-men 2 and Spiderman 2, too.
