So theres a few awesome new features that they are implementing into SC2:
- Global Play
- Multiplayer Resume from Replay
- Multiple Viewer Replays
- Clan/Group System and Unranked Matchmaking
This will be coming to Wings of Liberty through patch 1.5 and to Heart of the Swarm at launch. Looks like we'll all be able to play together real soon! Its awesome. Global Play is already being implemented into D3 so Im sure thats why they are putting it in SC2. And it makes sense. Some will argue that its about damn time too. lol.
