Adobe CS4 Announced|
Adobe announced Creative Suite 4 on 9/23/2008.
WISC expects to have CS4 items in stock in November. Until that time, any purchase of the current versions of CS3 can be upgraded to v4 for free! When you purchase, you will receive an email with details on how to apply for your upgrade, but the basic scenario is that you call Adobe, give them some specific information on your purchase, and they send you CS4 media.
