GIMP vs. Photoshop – What still needs to be done?

We all know that the GIMP is more or less the de-facto standard for image editing in Linux, where Adobe Photoshop is the standard on the Mac and Windows (and some Linux boxes using Crossover Office) The question is the following: Does GIMP have what it takes to dethrone Adobe Photoshop as the standard?

There are a couple good points made here, the primary being the name. Granted, the GIMP is not that professional sounding, so I have to agree. In the end, I’d rather see Photoshop ported to Linux reliably.
