Will I be able to preorder from GW Offical store?

Well i dont see it in the store, am i missing something? Yes, your 2 days early, look again on friday

Cause i want to get the bonus mission pack, and Beta Participation, Just to clarify, it's not a "beta participation"; it's a "sneak peak."

From the GW website:

"Players who pre-order Guild Wars: Eye of the North will gain access to the Sneak Peek Weekend, August 24–26, 2007, where they will be able to log into the game for a first look at Eye of the North. Players will be able to explore the Far Shiverpeaks region of the world, home of the barbaric Norn. Everything players obtain during the Sneak Peek Weekend, including items, XP, Heroes, and loot, will be permanent and available when the expansion goes live."

Just to clarify, it's not a "beta participation"; it's a "sneak peak." Its a sample before the main relese so could be described as a public BETA, do we have to be so picky

Its a sample before the main relese so could be described as a public BETA, do we have to be so picky Well, the reason I pointed it out is because I think "beta" implies a test.

Usually, things in Beta stage change before the release, and you usually cannot keep anything earned from a Beta.

The GWEN Sneak Peak is not a test, it is part of the real game, just a chance to play it earlier than anyone else.
