There was a loud uproar when Blizzard said that they would be splitting each of the three parts of the story behind Starcraft 2 into three installments. Sure each part would be as long as the sum of the original game. Sure the original game had Brood War. Fans saw it as a cash grab, a way to charge 60-bucks three times.

Heart of the Swarm is an expansion pack which will be priced as an expansion pack would. The standard edition will retail for $39.99 and is not hindered in any meaningful way. The Digital Deluxe edition will be priced at $59.99 and include only cutesy perks such as a Baneling pet for World of Warcraft or unique portraits for your character profile. The retail-exclusive Collector’s Edition includes the digital deluxe edition bonuses as well as novelties such as an art book, a mouse pad, a soundtrack, and a behind-the-scenes DVD and Blu-ray set.
Basically unless you want nerd-perks, the expansion is just $40.
The expansion pack will be released on March 12th, 2013.
