24P on the XL2 or other Canon camcorders isn't true 24P. The CCDs, even on the XLH1, are interlaced CCDs and progressive images must be interpolated from two interlaced fields.
While there is technically no direct licensing requirement in terms of patents/copyrights, etc.. for someone to produce a 24p/24FPS camera, it seems that most manufacturers are paying royalties to 24P, LLC. A "company" that holds the patent on acquiring 24 progressive frames per second from a digital imaging device, in order to replicate the appearance of film. Robert Faber, who holds the patent, is nothing more than a bully and it is outright extortion that he collects royalties for such a patent as it is very vague and extremely all-encompassing. Faber actually chased down Sony several years ago when they started shipping some of their intial 24p capable HD cameras and Sony lost (actually settled out of court). All licensing of 24P from Faber is handled confidentially on an individual basis and several cases have supposedly bordered on blackmail and illegal activity and they all involve a patent that should never have been granted in the first place. When Faber applied for his patent in '92, it was hardly an original idea then and various camera makers were already talking about such cameras and were playing with prototypes. It's almost as bad as the early '90s patent application by the Pizza Hut Corporation to patent their stuffed-crust pizza... A novelty of many pizza kitchens world-wide that has been around for at least a few hundred years. Perhaps I should go apply for a patent on 300FPS acquisition via a digital imaging system and then whenever upcoming digital cameras capable of 12.5X slow-mo arrive (240FPS digital are right around the corner), I can start collecting money for every slow-mo shot in every major motion picture.
Check out this link to a blurb at studiodaily.
Anyway, all that this shows is that Canon is developing or even preparing to release a 24P capable camera. Beyond that, I don't think anyone really knows what Canon is up to and they're very good at keeping quiet about their new products. It could be a new 720p consumer HDV camera or a 1080p pro camera, or anything in between. 24P and variable-rate progressive technology from 24P,LLC is currently used in just about every progressive-scan camera out there, including the Varicam, HVX200, DVX100, etc.. It's a small license, and could mean a lot of things, but it shows that Canon is taking a step towards a camera that has true progressive frame shooting abilities.
