Blizzard just keeps unveiling more and more surprises for their Blizzcon 2007. The latest announcement is that comedian and actor Jay Mohr will be performing as well as hosting the closing ceremonies of the event. In addition to this, he will also be serving as master of ceremonies for a series of live contests during the first night of the convention.

If the name doesn't ring a bell, you should know that Mohr has acted in box office hits such as Jerry Maguire and Pay It Forward, and is credited for creating, producing, and hosting the television show Last Comic Standing.

The president and co-founder of Blizzard Entertainment Mike Morhaime was very happy at acquiring his services for the event, stating that "we're [Blizzard] very pleased to have Jay Mohr on board for BlizzCon," and that "he's a great performer, and he'll really help us make this year's show memorable for our players."

This year's Blizzcon 2007 offers quite a lot for gamers such as hands-on game time with StarCraft II, contests, tournaments, new content for World of Warcraft players, developer discussion panels, and now live entertainment for attendees to enjoy. From what's been announced, it looks like this Blizzcon might be the biggest one to date.
