Wall Street was not impressed with what Apple had to offer at its opening keynote at the Worldwide Developers Conference this morning.

Though Apple refreshed its MacBook Pro, and MacBook Air lines, added an all new Retina-ready MacBook Pro and gave details on OS X Mountain Lion and iOS 6, Apple stock still took a significant nose dive.

Before the keynote began, Apple stock was up more than $8 a share in anticipation of the announcements.

At the time of this post, Apple stock was down $12 a share from its daily high, indicating that investors were disappointed that the keynote failed to highlight Apple’s next generation iPhone or the much fabled Apple-branded television set.

Are you surprised? What were you expecting from Apple’s keynote?
