Well heck, no sooner than they posted CS4 (that was what, a year ago?) here's CS5.

From a quick review, it seems very heavily geared towards the photo processing (i suppose that's to be expected, it is called PHOTOshop afterall right), though there's quite a few arts-oriented changes.

I thought the image they chose to showcase for the extended version was kind if interesting and strangely relevant to the site though
