I'm looking forward to playing with the new toys, and as per usual I suspect that Adobe will deliver even more than they advertise. Each of the tools in the existing suite are great, and for the most part market leaders. But for me, the best thing about CS, is the extra workflow benefits that are gained from using a suite of tools that are designed to play well with one another. I'm sure that the new versions bells and whistles are only half the story.... the real joy and advantages are being able to consistently use native formats such as .ai and .psd across all of the applications.
I imagine, or at least with any luck, this will end Quark's hold on the remainder of the print industry.... the one's who haven't yet had the foresight to leave old redundant tools behind.
I would hope that Adobe have re-introduced some help with dynamic site construction in GoLive, but at first glance this seems not to be the case.... shame!
