Disney seems to be considering adding a Star Wars-themed land at the Disneyland Resort in California, and is gauging interest via an online survey. A screenshot from a Disney survey shows the question "How interested would you be in visiting a Star Wars themed land at the Disneyland Resort?" and uses Yoda's lightsaber as the progress bar for the survey.
Notice that the survey asks about a "themed land" and not a "park", so this would suggest they are thinking of an addition to their existing parks rather than making it is own stand-alone park.
Currently, the Disneyland Resort contains the original Disneyland Park and the newer Disney California Adventure park. The former hasn't had a new themed land in 20 years since the addition of Mickey's Toon Town, while the latter recently opened a new themed land last year with Cars Land during a significant revamp to the entire park. Neither park has an abundance of room for new additions, but there are sections in both that could be repurposed to make room for a Star Wars land.
Or perhaps the Disney company, which recently purchased Lucasfilm and its Star Wars brand, is not set in stone on the matter at all. This is not the first time that Disney has considered the notion for one of their theme parks.
