Burnout Paradise planes just an April fools?

Back in July of last year, Criterion Games mentioned that it had been experimenting with airplanes as a potential Burnout Paradise add-on; however, with new info claiming that an announcement regarding this is due on April 1st, there's suspicion that such an update could be nothing more than a really long-running April Fool's joke. This information comes from the FAQ section on Criterion's website, where it was specifically stated to "check for an exciting announcement on April 1" for more on the inclusion of planes.
