Kevin 'Karune' Y has finally officially
addressed this issue which has concerned many fans since
rumours and hints of the monetization of battle.net 2.0 began to
surface. While some aspects of the new system may be require a fee,
simply playing the game online will be free. Karune had this to say:
"When a player buys the StarCraft II box at retail, they will have the
ability to play on the new Battle.net for free."
