Do you think Will & Kate will stand the pressure and last?

I've always been fascinated by a-list couples and how they handle all the public attention. I watched the royal wedding, teary-eyed, and I wish them both nothing but the best. They seem to truly love each other. However, I know everyone talk about how mature they are, but nothing can prepare you for the life that awaits them. Do you think it will last? No rude answers please, I'm not trying to bash the royal family, I just want to stimulate an insightful discussion with different point of views.
