I have not seen one of these new CLC comand units but we think it will plug straight into a W203. However, whether it will work with other devices already installed is another matter. Time will tell.
With actual hands-on experience with these i think i can provide a little input that might help.
Will it plug in and work - Yes no doubt.
Will the other components on the MOST work - Only a few because it uses a new media interface, i have a list somewhere but all i can remember from memory is the phone module wont work (since its now internal) but the CDC will.
