Although nothing has been said on the Apple site, I was just reading an article on AUPN which claims it does support editing plugins:

Apple has added the ability to create editing plug-ins for Aperture, which will, over time, revolutionize the program. Having an edit plug-in interface means that Aperture users will be able to do just about anything to their images. It’ll be possible to create plug-ins that replicate film effects, add borders, allow for selective edits like dodging and burning—the possibilities are pretty endless. For the purist who only wants to focus on Aperture’s image editing tools, there’s no need to ever add a plug-in, but for those who have been hankering to extend the program’s capabilities—your wish has been granted.
Oh for the one small ability to chose the external editor colourspace. I really hope I have overlooked something.
