Ok as you all know, all of us have been wait for a Diablo 3 announcment but that has yet to happen. I was surfing around moddb looking at mods and I came across a Half-Life 2 mod call Abaddon which is supposed to replicate Diablo 2 but it won't have the same story due to legal actions that would be taken by blizzard.
Diablo on Source Engine! Thats gonna take a long time
Theres another mod project I heard of, they're re-making Half Life 1 on the Source Engine and its called Black Mesa Source. To my knowledge its taken a long time in development and still isn't released. A Diablo Source might take even longer
Edit- After looking at the website I think it would be best if these guys had their own homepage and advertised the job positions on there
