A good article by a London-based Syrian journalist and this passage is all you need to know, if economical with your time:
Amidst these claims and counter-claims, in Egypt what appears to matter is not so much changing the rules of power than the affiliations of those who have it—and who therefore enjoys its spoils. It is a zero-sum game where enemies must be crushed and power sought and accumulated for its own sake.

From my very limited perspective it is interesting that the MB in Tunisia is acting in a different manner; their leaders spent decades abroad, notably in the UK and those in Egypt were at home, under the dictatorship and often in jail. Becoming a democrat in power appears to be harder in Egypt.

Yes I acknowledge there is an argument that the MB is not a true believer in democracy.
