Confused, but nothing new

Hi everybody, me yet again, but different question this time.
Have just installed Silent Hunter Original by SSI and awaiting Arrival of Silent Hunter Commanders Edition. Have been reading your forums re Silent Hunter 2 and Pacific Aces, and here is my Question.
Has SHCE become an English Version of SH2 because a long long time ago I Purchased SH2 and took it back the same day, because the Whole thing was in German including the Gauges and Switches that opperate the Submarine. And if I remember correctly was opperating in the Atlantic Ocean not the Pacific.
If I purchase pacific Aces Super DVD do I have to purchase anything else to go with it.
Many thanks
Paul
