Amazon.com has apparently spilled the beans on the shipping date for Adobe's CS3 suite, including Photoshop, as April 20th. As we've mentioned before, Adobe has a special event planned for Tuesday (March 27) presumably to announce this very thing. Amazon's Canadian store has Photoshop, for instance, while the US store has CS3 Web Premium, with both listings showing: "This item will be released on April 20, 2007." So now you know just how long you get to keep using that Photoshop CS3 beta. MacNN has a nice post summarizing all of the pricing and suite information leaked by Amazon.
