Starcraftwire.net translated a German players post who claims to have inside knowledge of the Starcraft 2 Beta. The breakdown is as follows:

We have translated the German fan's summary of the StarCraft 2 info summary:

* Blizzard has a fixed date for the beta, however, it's still a secret.
* The multiplayer part of the game is basically done, except for a few details.
* There will be several opportunities to participate in the beta to come (including competitions, perhaps a kind of story competition or similar).
* In the current build (internally at Blizzard), there is a Dark Pylon with a cool ability, which enables Probes to harvest faster within the reach of the Pylon.
* The Command Center can now use a new cool ability that creates a "bigger" SCV which is better at harvesting.
* Supply depots can be upgraded to give +2 Supply.
* Xordiah, who is a "Protoss Fetishist", is Very Happy.
* This build's Immortals are extremely strong.

Blizzard has set up a site called Starcraft 2 Battle Report that gives players an in depth look at the state of the game. The first battle report is Matt Kooper (Protoss) vs David Kim (Terran). The video shows fans the Terran Marauder, Hellian, and Banshee units and elaborates on the Protoss' Zealots, Colossus' and Stalker units.

A Starcraft 2 release by the end of 2009 should be extremely probable based on the footage of the game. The video states that it is in an Alpha state but the game looks extremely polished and is in a competitevely playable state.

The Terran as it looks still have bunkers much like the original Starcraft and have to rely on heavy support to battle with the Protoss army. The protoss now can warp units in much more effectively using pylons (a great new strategy for the race) and can resupply the frontlines quickly.

This new Starcraft 2 video series is an excellent move by Blizzard providing much needed information as to the progress of it's development.

The current Starcraft 2 downloads include video, fansite kits, wallpapers, and some mobile ringtones and phone wallpapers. You can find them mostly on the Blizzard owned site http://mobile.blizzard.com . Most of the wallpapers are around 1.99 which isn't too bad if you want a picture of Raynor or Kerrigan on your cell phone.

The Fansite kit is a must if you plan on making a blog about Starcraft 2. Most of the pictures on this site are pulled from the fansite kit and custom edited for layouts sake. There are 5 official wallpapers available for download from the site and they are Kerrigan, A marine in combat, a marine getting nuked, Zertaul, and a large Starcraft 2 logo.

Unfortunately there are really no other quality starcraft 2 downloads that are official from blizzard. With the months prior to a Starcraft 2 beta or Starcraft 2 release date we should see some more content from the gaming giant.
