Assassin's Creed ending (Spoilers)

I only finished AC1 and am going to get AC2 but I have a question

What happens to the so called Pieces of Eden and Abstergo during AC2?

What happens to desmond?

WTF are those symbols in the Abstergo HQ

How about you actually play the game and then you'll know what happens? Doesn't that sound logical to you? You're seriously asking for spoilers before you even play the game? You're asking for the ending of the second game before you even buy it?

It will explain itself in the next game

What I'm really wondering was WTF were the stuff written in blood at the end of AC1
