I know what a pitch is. The most hilarious - and, frankly, incompetent - feature of this "just the pitch, never the plan" argument is that it means Universal had planned FROM THE BEGINNING to spread Nintendo out over all their parks, yet didn't bother to pitch that to Nintendo. WHAT?!?!? You don't understand pitching if you think that's what happened. If Universal KNEW they had Harry Potter II on their hands (which they didn't) and KNEW that it was going to be in multiple parks (which they didn't), the chance that they wouldn't have pitched that idea directly to Nintendo is approximately 0.00000000000000 PERCENT, give or take a few hundred zeroes. You don't pitch 33% of a plan!!
Furthermore, in the protective world of Nintendo, a pitch requires more than concept art and half-baked ideas. They take years creating their Mario and Zelda and Pokemon games, so they weren't going to respond to anything less effort-wise from Universal Creative. UC flew Nintendo executives to Florida, showed them Diagon Alley and Hogsmeade and told them "Oh, look what we CAN do!" Then they toured the exact plot of land their plans were drawn for and told them, "This is what we WILL do!" Nintendo wasn't going to climb aboard with nothing more than blue sky rainbow unicorn dreams. They needed details and they needed promises, the same as JK Rowling wasn't going to sign on unless she had something presented to her that was closer to "final draft" than "opening pitch".
And that works both ways. UC isn't going to present Nintendo with fairy dust magic fantasy art and then give Nintendo final approval. Because then UC runs the risk of not being able to turn the fairy dust magic fantasy art into reality, forcing Nintendo to say, "No. Give us the rainbow unicorn dreams you promised us." Unless Universal wants headaches, delays and threats to end the partnership in their future, their original "pitch" was going to have to be pretty close to their final "pitch".
That's how things work in the business world. Even in the business world that builds rainbow unicorn magic fantasy dreams.
