Early results from the election in Sudan show that a split between north and south is likely. A referendum held over the past week allowed Sudanese citizens around the world to vote on independence, and the results that have been streaming in over the past few days show that secession is extremely likely. A BBC report said that more than 97% of the European Sudanese diaspora had voted for a new state, although full results from the vote are not expected until next month.http://www.care2.com/causes/politics/blog/early-results-show-that-sudan-may-split/
This means that it is more likely than not that less Sudanese will be killing each other in the future.
It does not mean that either Northern or Southern Sudan will enter an era of peace, prosperity or democracy.
