Still using Creative Suite 1? Upgrade pricing won’t last much longer…

Over on his block, John Nack of Adobe points out that if you still own Creative Suite 1 and you want to upgrade to Creative Suite 4, you should do so soon, as Adobe has a “3 versions back” policy and you won’t be able to upgrade CS1 to CS5 for the upgrade price once CS5 is announced. There’s some talk in the comments of his post that if you upgrade to CS4 and CS5 is announced within 30 days of your upgrade, you’ll get a free upgrade to CS5—Nack hasn’t confirmed this.
