Yeah, Episode VII is part of the title. It was not included in the orignal trilogy until the Prequels came out. A New Hope was there, but never used. The marketed the PT as Episode I, Episode II, and Episode III to emphasize their place in the timeline and the official title of IV, V, and VI were updated at that time. Technically that has been their title from the release of V and the rerelease of IV in 1981 with the new crawl. But it was silly to refer to 4, 5, and 6, when there were no 1, 2, or 3. Now there is 7 and 8 and 9 are coming soon.
