Here's an oddity for you; it's Friday in the Arab world, and the big protest of the day is... against the Muslim Brotherhood. The Egyptian street seems to have little mercy for Mursi's power grab, where he essentally declared himself dictator until a new constitution is set up. Mubarak with a prayer rug is about right, except that Mubarak was one of the last Cold War SOBs that could be counted on to be loosely pro-US.
With Mursi, all bets are off. The geopolitics of this might be tempered by Israeli muscle poised to pounce if Mursi becomes too pro-Hamas, but the internal politics could get very messy, especially if Mursi decides to take the lead of a lot of Africa's Big Men and take dictatorial charge for as long as he can.
