Will the seventh Harry Potter book, due out July 21, really be the final one in the series?

J.K. Rowling, the author of the best-selling fantasy novels, has set fans buzzing this week by refusing to rule out an eighth installment, after breaking down in tears while finishing the seventh.

“Never say never,” a spokesman for Rowling told the U.K.’s Telegraph, adding: “It’s not saying that she definitely is [going to write another title], and it’s not saying that she definitely isn’t. I cannot comment further.”

Rowling’s equivocations will add to already heated speculation about which two characters might die in the seventh book.

Among those who are wondering how things will turn out: Daniel Radcliffe and Rupert Grint, who play Harry and Ron in the Potter films. At the world premiere of the fifth film, Harry Potter and the Order of the Phoenix, in Los Angeles on Sunday, the actors revealed their own dream scenarios – envisioning plots that would adapt well to the screen.

“The seventh film, entirely nude!” Radcliffe joked to PEOPLE.

Added Grint: “If Ron could die, I wouldn’t be that sad, because that would be a really cool scene – if it was like, a really heroic moment,” he says.

However the series ends, Grint’s future seems secure, now that he’s invested in … an ice-cream truck?!

“Oh yeah, I drive it everywhere, it’s really good,” says Grint. “It’s got the freezer, and the little whipping machine.”

The 18-year-old actor says buying the van was a childhood dream come true. Plus, he says, it provides some job security. “If this doesn’t work out, I’ve always got a backup plan,” he jokes.

Emma Watson, who plays Hermione Granger, drew plenty of attention at the premiere as well – thanks to her newly blonde locks and her Chanel dress, which was adorned with a multitude of pill-shaped buttons and pins.

Asked why she went blonde, she replied: “Summer, and it just seems to suit me better. It’s more like my natural color. … And blondes have more fun.” As for the dress, she said, “I thought that it was really unique, and kinda fun, and young, and different. I love this dress.”

Like many 17-year-olds, Watson added that she does love her clothes shopping. “It’s probably what I spend most of my money on,” she said.

The premiere was held Sunday at Grauman’s Chinese Theater in Hollywood, with an afterparty at Jim Henson Studios.
