Boy Genius has an unconfirmed source claiming that, as part of Apple's rumored iLife 2010, long-ignored iDVD will finally see an update -- and that update will be support for iTunes LP (and we're assuming iTunes Extras) creation/authoring.
It certainly makes sense, not only to keep iDVD relevant (though would it need a name refresh as well?), but also since Apple recently made iTunes LP and iTunes Extra (and TuneKit) resources available to developers. A consumer/prosumer-friendly development environment, similar to GarageBand or iMovie, makes the kind of sense that does.
