It says...
"
After Star Wars became a success, Lucas announced his intention to turn the film into a series, originally totaling nine films (later pared back to six). Consequently, most reissue prints now feature the title Star Wars: Episode IV?A New Hope, with The Empire Strikes Back (1980) and Return of the Jedi (1983) serving as Episodes Five and Six in the serial, and Star Wars: Episode I - The Phantom Menace (1999) going back to the myth's beginnings. ?

This site:

Apologies to Dork Jedi, he's right.
But for those of you who didn't know about the original 9-movie plan, now you know.
