What's behind the change in Egyptian army?

Has the Egyptian military reached an accord with President Hosni Mubarak and/or his apparent designated successor, Omar Suleiman, already? I can't see what else would lead the army, after saying Monday it wouldn't fire on protesters, to now tell them, in essence, they've been heard and they need to go home.

And, how many will listen? How many will listen if the bullets start flying? How many soldiers will start the bullets flying?

So far, the military hasn't fired those bullets; violence has been between pro- and anti-Mubarak citizen groups, the former allegedly largely comprised of paid young street toughs.

As I said yesterday, I think something further "gives," one way or other, by the end of this week.

I expect that by Friday evening, the army will have taken a good measure of both Mubarak and the opposition, any promises by Mubarak and other issues, and will know more about where it wants to stand.
