hmmm.... let me see.... "Startcraft 2" if thats what it will be called won't just be an improvement on the old game. you say they will get "new units" as if all the old stuff remains. Look at bliz's other games. Diablo 1 turned into Diablo 2, and many of us know what a difference you see there, same as for warIII. EXPANSIONS and PATCHES are what are used for improvements. Post the URL, i dare you...
