Not always, but close. It was a few months after release that the "Episode IV: A New Hope" was added, when it became obvious the movie was a hit and the sequels would sell.
I don't know why this is such a hot topic in this thread, but I'll clear it up.
The original plot that George Lucas wrote for Star Wars contained NINE different volumes. The last three are the story of Luke's son, that Luke then redeems from the dark side. (He never fleshed this part of the story out well, it was meant as "comes full circle" type of thing)
The first movie released was done so that it could be a one-off if it didn't catch on. (In the first version, the Death Star wasn't destroyed then, which is why they built a second one in Return of the Jedi. But it would have been difficult to have a one-off movie with the Death Star staying around, so it was changed.)
Most of the major plot points from the prequel trilogy were well known before the movies were made, especially the Anakin gets burned by lava by Obi-Wan part. That is written into the novelization of episode IV. The story stayed pretty true to what he wrote in the 70s.
Now, as far as limited by technology being part of the reason that Lucas started with episode IV, thats not true. He started with IV because it was the most interesting part of the story, the intersection of the two different timelines, and the turn around after the "darkness" of episode III. Technology WAS the major reason that Lucas has gone back to edit the original trilogy multiple times to put scenes the way he originally envisioned them.

On topic: Universal STILL hasn't completely secured the rights to Harry Potter. However, yes, they will be the ones to get them. Disney doesn't want to be part of it because of one of Rowling's terms of the agreement.
Well, that's not exactly how it happened.
Star Wars was one story: The Star Wars. George Lucas realized he couldn't make the whole thing because it was simply too long. So he took most of the story and put in on the shelf in case he was ever to make the rest of the story. He took the first 1/3 of the story and made Star Wars. (But it is true that the Death Star was originally supposed to take part in the later part of the story but was introduced in the beginning.) But there was not 9 volumes. However in order to write the original Star Wars story, he had to have a lot of back story for where everyone came from, thus what the prequels would eventually be based on.
He always wanted to call it Episode IV, because Star Wars is based off all the old serials. But the people in charge of the time thought people would be too confused so they didn't allow him to do it. However, after the success and the confirmation that a sequeal would be made (The Empire Strikes Back) George Lucas rereleased the original Star Wars movie as Episode IV: A New Hope.
Lucas did at one point intend to eventually make 9 movies, but now feels he's getting too old and decided that the first 6 movies really are what the story is about: the life of Anakin Skywalker. (Though I trully doubt that it is the definate end of Star Wars films).
As for Lord of the Rings being the greatest trilogy ever...............................................................................I don't think so.
They are so boring, have too much backstory, side story, and other story that is relevant to the movie, too many funky names, and finally takes
WAY too long.
I attempted to watch the end of the final movie, and was like "What are they waiting for, just end it!"
Lord of the Rings cannot stand on their own. One must watch the first to understand the second, and watch the second in order to understand the third.
It definately wouldn't fit in a Disney park.
Although, if Harry Potter ever was made an attraction, I would assume that it wouldn't follow a particular story, and be sort of a seperate story or spin-off that doesn't necesarily follow the story line.
