Quote fromThe good news from this video is that:
1.The five classes HAVE been decided. (Rob: "...they are playable back at the home office")
2.They have made progress on the single player campaign ("Act I is pretty much playable")
3.This version of the game has been in development for 3 years (Blizz is usually on a 4 year dev cycle)
So basically he admitted it just comes down to content. They have to add more levels, skills, items, etc., The core game mechanics and engine and planning is basically done.
Yeah, the core is done. So only polish left in Blizzard style. So like 2-3 years..........
