Diablo 3 - Patch 1.05 Sneak Peek

Blizzard has outlined the changes for Diablo III v1.05:

Defensive Skill Changes
In our eternal quest to promote build diversity; we’ll be making changes to defensive skills across the board while simultaneously reducing incoming damage. The net result is a survivability buff for players, and an increase in build options as defensive abilities become less “mandatory.”
New Event: Infernal Machine
The Infernal Machine is a device that will allow level-60 players to battle “uber” versions of some of Sanctuary’s most nefarious bosses. While the rewards for defeating these bosses will be great, some assembly is required.
New System: Monster Power
Similar to the “Players 8” command in Diablo II, the Monster Power system is designed to give players more control over how challenging enemies are in each difficulty.

Wait, does this patch make the game easier still? Well, on normal that is.

Shouldn't really affect normal, it's for the higher difficulties where you were forced to build defensive to survive. They have to describe it as a buff because everyone complains when they hear that they nerfed defensive skills.

It's all in how you phrase it: Previously the skill "suck it" did 60 damage and average mob had 100 hit points. We've increased the skill damage to 400! In an unrelated change, average mob HP is now 1000.
