I'm guessing a release date wasn't in effect yet, and someone put them out by mistake.
Driving from Vegas to San Diego for comic-con, my wife and I stopped at a Toys R Us on the way there. They had an entire isle already out of the Clone Wars figures 2 days before the release date.
We picked a few things up, went to the register.
Left the store completely empty handed! lol The sales clerk couldn't get them to ring up, they came up "date sensitive" or something like that, and the manager freaked when she saw they were out. Apologizing left and right as she quickly took them away from us and called her stock room to get everything pulled
*shrugs* some people just can't read packing boxes
