If you carefully analyze Blizzard's work over the past 5 years, there's not much to show for it.

They have had nothing but let down after let down, failed projects and empty promises since WoW came out. Where is Starcraft Ghost? What happened to Starcraft II? Or should I say, II, III, and IV? Why can players have invulnerable phoenixes in WC3, crash other players computers in D2, and do god knows what in SC. Why does it take 5 years between updates for their games, when they have only ~3 games to worry about? They are making hundreds of millions of dollars through World of Warcraft, and can't be arsed to create updates for legacy games that could be done on budgets of around $1000- a few hours of work.
