German gaming site GamersUnity is reporting that a hastily deleted post on the official Diablo III forums has confirmed that the game will not be carrying a LAN play feature just like StarCraft II.
The post, reportedly made by a Battle.Net community manager, posits the same reasons that LAN play is being disabled in StarCraft II: to curb piracy. Here's a snippet off the deleted post:
More so than overbearing/invasive anti-piracy measures that would affect everyone who buys the game regardless of how they're going to play it instead of just those that may want a LAN feature? I would doubt it.
I don't know a lot about it, Diablo III isn't really facing the brunt of the Battle.net 2.0 features just yet, but I think that removing LAN in an attempt to avoid more severe anti-piracy measures is pretty cool. We're saying "Hey, we're pretty sure you're going to love our game. The multiplayer is really the best part though. In order to get in on that that we'd just like to make sure you bought the game. Cool?
This has yet to be confirmed officially by Blizzard, but given their push to turn Battle.Net into an even bigger multiplayer hub for their titles than it was before, I wouldn't be surprised if it turns out to be true.
