Blizzard has confirmed that StarCraft is currently being worked on, however it seems that StarCraft has been on the backburner since Diablo 2 has had 3 patches this year and WarCraft 3 has had 1, though another patch for WC3 seems imminent. Of the three games, StarCraft players are not very vocal on the Battle.net forums, which may seem like we're a small community even though we're really not. I'm posting this in hopes that you will support StarCraft simply by upvoting, and maybe even commenting on, this topic that I made on the Battle.net forums:
