Diablo 3 informations

Ray of Frost is a wizard spell that damages and freezes enemies caught in the beam, slowing their movement and attack speed.

Sweeping Wind is a combo skill that lashes out against all enemies surrounding the monk, creating a vortex of damaging wind that increases in damage and radius across three stages.
Crimson - Beam increases in damage the longer it remains in use, to a cap.

Indigo - Wizard is surrounded by a swirling vortex of sleet, damaging any foes that come into contact.

Obsidian - Decreases beam damage, but increases reduction in target movement and attack speed.

Golden - Arcane Power cost reduced.
Whirlwind is an iconic Diablo II skill, wherein the barbarian spins furiously and damages any enemies in his path.

Alabaster - Enemies slain by Ray of Frost have a chance to leave an area of ice on the ground where they die, damaging other enemies if they move through it.

As for the no LAN play, I think everyone saw that coming from a mile away. Not for me.

lol that's just a random Q4 date that they stuck on there for the heck of it. It was announce to be coming sometime in 2011, but I would hazard at a January release.

They wish they knew the ETA
One thing about blizzard is they know how to make games. They also know how to market them.
And what better way to announce one of the most anticipated Betas at their own convention –Blizzcon
(that fired tester said the same I know)
Have a look at the blizzcon site - notice how d3 gets the prominance through out the site and if SC2 beta was anything to go on in terms of how long the retail will be released after beta – is about 6months.
If it means the game wont be as buggy or whateva then idont mind waiting for D3 to be released.
D1 and D2 were just awesome. Even the music...just watched some vids of the music on youtube, brings back such memories.

Date will be released at blizzcon 2011 which is end of October, as timeline table from blizzard show d3 should be end of this year, have to wait for blizzcon and see.
