We can only hope that there will be a positive outcome. The bad news is that even if Mubarak goes, and it looks like he will have to, the chances are that the corrupt apparatus that surrounds him will survive and that the establishment will gradually regain control. There is no clear focus for the revolution other than the removal of the regime and its replacement by an open plural democracy. We can only hope that a genuine secular democracy will be the eventual outcome.
What the Egyptian revolution has exposed is not just the oppression and the wasted lives of Egyptians, but has also exposed the cynicism of western governments, including the USA and UK, who have been happy to support this regime as long as it brought "stability". But what is this "stability"? It means that corporations can operate and make profits without fear of any interference, and in particular, can exploit the resources in the region. Western governments have been acting in the interests of the corporations - and screw what that means for the people. That is capitalism in action and that is what really matters to our governments, that is the 'bottom line'. When will people realise that the same applies here?
