I purchased Supertunia Giant Pink for my flower box. They are loaded with blooms, but all the stems seem to be growing in an upright position, as if they're reaching for the sky. I'm hoping they'll eventually overflow (cascade) out of the flower box. Will this eventually happen or did I purchase the wrong kind of petunia variety?

Are they getting plenty of light? Without enough light, they will be more leggy and act this way. These are, in fact, a trailing type petunia and should begin cascading over the rim of your flower box. You can try pinching the growing tips to make it more bushy, which should help it quit growing up.
