So instead of having 1 million different threads saying which guild downed what boss first I thought I would create a thread to keep all this kind of info.
Try not to start any flame wars and to keep things peaceful 10 mans and 25 mans are different races.
Any US guilds killed anything yet?
Current progress can be seen at:

Currently nobody with a boss down!
25 man progress:
Method currently winning the 25 man race.
10 man progress:
Arctica are currently winning.
