"It’s my understanding that when the next version of Photoshop and the Creative Suite is released, if you do not already own Photoshop version CS5 or CS5.5 (or the 5 or 5.5 Creative Suite):
(a) You will not be eligible to upgrade to Photoshop CS6 (or the CS6 Creative Suite). Instead the only way to get Photoshop CS6 at that point will be to repurchase the entire product again at its full price (presumably $699 US). If you’re a CS4 Creative Suite User, you’ll have to buy the entire suite all over again to move to CS6.
(b) For Photoshop CS4, or CS3 users, their only real option is to pay to upgrade now to CS5.5 (though you are offering a 20% upgrade discount upgrade until the end of the year), and then to pay again to upgrade when Photoshop CS6 is released, or sign up for your new monthly subscription plan."
