There was at least one Asgard ship fighting the Ori.
The ship that blew up must have been the one Daniel wasn't on, unless he's going to do his "Oh I'm ascended, oh wait, no I'm not" routine again. So it must have been the American one that blew.
Did anyone get the parallels between the story of King Arthur's conception and that of Vala's baby? Perhaps her baby is to be the Ori's Arthur.
Of course Daniel has to go back to Camelot, meet Arfur, get the SanGreal, whup the Ori and maybe that'll stop their ships working or summat.
Lousy tactics from our guys by the way. They should all have concentrated their fire on one part of one of the ships to try to take it out. Once that's done they all concentrate on another. Spreading their fire about like that was just plain dumb; have they never played Command & Conquer?

Normally I wouldn't expect a single Wraith hive ship to be more than our lot could handle, especially with Asgard help. I guess they're all a little busy right now though.
