I found this article
which gives a little more info on what,s coming for CS4.
I,m pretty happy about OnLocation for mac.
[edited: sorry the direct link keeps automatically changing to http://library.http://www.teenink.co.../adobe_cs4.php.
If you are interested in the article then just go to creative cow .com and go to the "NEWS" tab, scroll down to CS4 icons.
I don,t know if this is some kind of reduser hack or any link to creative cow.
wish I knew why it did that....
