The point is, if you are going to include almost 30 year olds into Generation Y, then you have people who have tons of memories of Diana. I am just a year older than William, and while I can't remember the wedding, I can remember a lot about Diana.
Again give it thirty years. She isn't princess of wales yet. Let her have her own tiara, her own identity, apart from her mother in law. If you think no one but royal fanatics will draw a link, I'm sorry but you're wrong. Every magazine, television show, website and newspaper keeps bringing up Diana with this wedding. Every single article has mentioned Diana's ring. Americans who watch anything like et or access hollywood, will have seen the ten minute tribute to Diana with 20 seconds about the wedding, for william and kate's wedding announcement. It is the baby boomers and Generation X in control of the media right now, and will be for decades to come. They will draw comparisons for a long time to come. And as long as they continue to put Diana's picture all over the news, every time a story is about William, she will be alive. The fact is that the media will not allow Diana to RIP, 14 years after her death she still is in magazines and on tv. When William and Kate get pregnant, the pregnancy photos of Diana will come out. When the baby is born, pictures of Will and his mum when he is a baby will be on every magazine.
