There's more to the Arab Spring than Egypt.
It's really far too early to call how it all will end, as all countries have different things going on and many are in rather different situations. It's worth noting however that the typical Arab leader had ruled 20+ years before the Arab Spring. From that perspective changing four of them (Libya, Tunisia, Egypt and Yemen) in basicly one sweep is a lot of change relatively speaking.
There are countries where pretty much nothing changed. (Bahrain I think being the saddest example, as the peaceful uprising was put down with brutality with the western media mostly being silent.)
Then there are places where I think it's safe to say that things will change for the better. Jordan I think is the best example of that. I recommend checking out King Abdullah II visiting the Daily Show.
He might not be the mr. nice guy he likes to appear as, but he is not a tyrant either.

But more generally, I think it's naïve to say that nothing has changed. Simply the amount of new free discussion in the Arab world is a huge change and will certainly change things over time.
Also, the civil uprisings are not the only thing happening there, and trying to see everything through that lense will result in a distorted view. As always there are multiple forces at work, economical issues being some of the most important.
We can now also see more of what's really going on in those countries, which easily leads to the perception of things being worse, when actually it's more about us seeing problems that have already been developing.
But there will certainly be a lot of violence still. It's typical for revolutions.
