All these reports talk about "possibility" and "might" and "maybe."
Count Mubarak gone only when he is really gone. Until then this might be another attempt to bluff the protesters into going home.
Even if Mubarak leaves, for Sulieman to retain power means the Mubarak government machine remains in place, with all existing policies, including obeisance to Israel and the US.
The good news is that this is a major political defeat and loss of face for every world leader who supported Mubarak.
In the case of Barack Obama, the world watched him toss the founding principles of the United States into a shredder in order to obey Israel's desire for Mubarak to remain, and of course in hindsight, did so to no real purpose.
