Just because its on Starwars.com doesn't mean that it has to be star wars related. Its just that Lucasfilm doesn't exactly control a big Howard The Duck website, for example, so that is the next best alternative.
Although the idea of the Ewoks movies are intriguing. I think that they are also good possiblities.
