According to CNet, Adobe is planning to expand on their web-based offerings. Here's a a taste:
Adobe has watched with interest as outfits like Google have acquired or developed several successful ad-supported services over the past few years, and has decided to throw its hat into the ring and take one of its most famous products into the on-line arena. The web-based Photoshop could face some stiff competition not only from existing free image editing software but other web-based solutions.
With Adobe planning on using advertising to support the web-based Photoshop, it will be interesting to see if or how they plan on promoting retail versions of their software. With the Adobe online store, they could potentially include links to features that are not present in the web-based version but could link you to a trial of the full product or the ability to purchase the full product. In this sense, the company who might get the most exposure from the web-based Photoshop is very likely to be Adobe themselves.
