If you were looking for Oni info, then it was a good place to be (despite the relative chaos). As for Halo info, very little, if any was given, so don't worry if you missed out on it. About the only remotely Halo related tidbit was that Oni will not be set in the same universe as Halo or Marathon...

For a wrap up of the interview, you might want to check out Onicore in the next day or so, as they're sure to be dissecting it in more detail than I will be.
