According to this post on the Creative Solutions PR @ Adobe blog, for a limited time Adobe is offering a special introductory offer that allows those with older qualifying versions of CS products to upgrade at the same discount as those upgrading from CS3.
So, if you skipped the CS3 upgrade the last time around and are still working with CS2, you can upgrade to CS4 for the same price as if you had kept up with the CS3 Joneses.
Don’t believe me? Under the question “Why is Adobe offering tiered upgrade pricing?” on Adobe’s Creative Suite FAQ Page, the second paragraph reads:
As a special introductory offer, customers with earlier versions of Adobe Creative Suite, Macromedia Studio, and Adobe Production Studio software can upgrade for the same price as those moving from Creative Suite 3–up to a USD$200 savings! This offer ends on February 28, 2009, in North America.
