Within hours, Apple (Nasdaq: AAPL) will unveil the third sibling in its line of ultra-successful tablet computers. The iPad has been a monster hit for Apple, selling more than 55 million units since its introduction just under two years ago -- that's a meteoric rise unmatched by any other product in the company's lineup. But will the new tablet be worth the wait? Here are some of the features we expect to see.

Even with all the emphasis on video, the iPad 3 won't be solely for homebrewed Hitchcocks. Apple's tablet is also serious competition for the e-readers and smaller tablets offered up by Barnes & Noble and Amazon.com. And with Apple's growing App Store, there's something to keep everyone happy. The iPad might only be 2 years old, but it's wise beyond its years.
