Couple more corrections:
Q: How long will the beta submissions be open?
A: It will be open for about 2 weeks after it starts
It will be open for about 1 week after the beta 1 starts. If you miss beta 1, you'll get another chance when beta 2 launches in a few months.
Q: What is the Shipping cost?
A: about 10 euro's to Europe and 5 to the US.
You should specify that it's the shipping cost for the full, final game. We won't be shipping beta discs out.
Q: Can I get the game in another language then english?
A: Not in preorder or in beta. Only the english version is available (but will properly change at release)
Stardock will only be selling the final version in English. Other language versions (French, Spanish, German, Italian and Dutch) may be made available after release via Stardock Central. This is all still pretty undetermined, however.
Q: Will I be able to play all sides?
A: Wouldn't be much of a beta if you couldn't.
Not in beta 1. For beta 1 players will only be able to play as, and against, the Trader Emergency Coalition. The other races will be made available as the beta progresses. We'd like to get some structured feedback on how each race plays, so doing it one-at-a-time will be a lot easier than a free-for-all right out of the gate. 
Q: Whats the requirement to play in the beta?
A: We expect it to be able to run on a, 2ghz, 512mb of ram, and on a crappy graphics card
Minimum specs (in general) will be: 1.8 GHz processor, 512 MB RAM (1 GB RAM in Vista), and a 128 MB DirectX 9 3D video card.
