i dont think Adobe will do anything major changes to any of the macromedia products. maybe just change the name to adobe something and work on integration of some of the products like photoshop and flash.

they will have to see how the customers react to the buying of macromedia.

i am not sure but didnt adobe acquire cool edit and change it into adobe audition. i am not sure. if yes then they did nothing but change the name of the software
small changes nothing major if that is the case.

anyway we will just have to wait and see.....
