That is absolute hogwash! CS2 has nothing to do with CS3 (or CS4) nor viceversa.
It's entirely your call. Same with CS4. You can keep prior versions or uninstall them. Your choice.
If the upgrade installer does not find a serial number in a previous version, it will simply prompt you for the old serial number as well as the new one.
However, if you're going to uninstall CS3, (1) use the Adobe Uninstaller in your Utilities folder:
HardDrive/Applications/Utilities/Adobe/…
DO NOT just drag things to the trash like we could with CS2 and earlier Versions, and (d) uninstall CS3 BEFORE installing CS4.
