I'm kinda predicting that the competitive scene for for Starcraft will split into two once Starcraft 2 comes out. Some people that are hardcore Starcraft 1 fans will outright dislike the new units and gameplay of Starcraft 2, and there will always be lots of competitive Starcraft players that dislike Starcraft 2 because it will "take less skill" to play. The impact of SC2 on the competitive scene will probably be like the impact of Brawl on the competitive Super Smash Bros. scene.
Anyway, discuss the impact of SC2 on the competitive SC scene in general.
