EA will unleash Battlefield Heroes in the Summer 2008. According to the press release, "Battlefield Heroes is EA's first title that is offered completely for free, and features a built-in matchmaking system to ensure that players of equal skill are paired together for fair play."  
From the website:

• Battlefield Heroes™ is a brand new Play 4 Free™ game from the people that brought you the multi-million selling Battlefield 1942™ and Battlefield 2™
• It's a fun cartoon-style shooter which caters to players of all skill levels – easy to pick up and play, but with deep character development
• It will be released for the PC as a free download in Summer 2008

Most important, "With the new online model, we will continually add new content to keep the game fresh and keep players engaged, while integrating player feedback in real time." What do you think? Will you spend your hours online playing? Do you think this model will expand and bring competition? How do you think the companies will earn revenue from the online game model?
