It looks like most conferences are trying to be "4 time zone conferences" so they can offer their TV partners multiple games in a day in all windows.
Now, I don't necessarily think that formula, that the BigTen is following and the BigXII is doing as well, will work for the pac, but it is something other conferences are working towards.
I also think they are trying hard to chop the heads of the other G5 conference and take as many of the other top G5 teams as possible.
