The difficult part is always what comes after a revolution. Having the military in charge isn't necessarily a good thing, and whether Egypt does get a democratic government will now depend upon how the military behaves.
Not to mention that a democratic government, in itself, doesn't guarantee anything - large-scale corruption and incompetence are still a very real possibility.
Still, hopefully a step in the right direction - more options are now available to the Egyptian people.
Not just a real possibility, but a very likely one. I recall that in one interview, a protester was complaining about the lack of economic opportunity. "The supervisor hires all his nephews! Regular people can't get any hours!" (Or something to that effect.)
No matter how awesome the new regime is, I doubt they can fix this. Sad fact: many of Egypt's problems are inflicted by the people on themselves, not by Mubarak.
Alas, I can't find it now, but I recall reading a Foreign Policy article a few months ago which quoted one Egyptian as saying something like 'Mubarak is problem, but the much bigger problem is that this country has a million little Mubaraks, tiny totalitarians who rule their tiny fiefdoms with a tiny (iron) fist'; it seems that getting rid of Mubarak will have been much easier than displacing or reforming all the little Mubaraks.
That seems similar to the situation in Tunisia, and I'd say it's a common pattern that replicates itself whenever a country is under a dictatorship for decades.
This is a really incredible success of the Egyptian people, but it's just the first step of De-Mubarak-ification.

Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience.
