Since iPhoto works with any image that already exists, I think that will be the way to go with expanding the hardware that it works with. Although they'll add some stuff, I think they need to streamline the workflow for importing images brought in from other software, like say a scanner that doesn't run under X native. I couldn't get my mother to understand the workflow of scanning, importing, exporting as jpeg, throwing away the original bitmap and importing the jpeg. This workflow needs improvement. :-(
