With the recent release of Lightroom 4, I again finding myself wondering if I should convert to it from Aperture. I find the Lightroom user-interface rather awkward. I particularly don't like the lack of managed files as well as the module-based workflow. However, it does seem like Adobe is more interested in actively updating their software than Apple is with Aperture.
Is anyone else concerned that Apple has lost interest in continuing to advance Aperture? I know how secretively Apple is with software releases, but has anyone heard any reliable rumblings about a potential Aperture update on the horizon?
