The dividend will be raised but not back to what it once was (which was double the current level). After the federal case against them is resolved and the liabilities are made certain, then you can expect a much bigger divvy raise. That may not be for a few years.
All that said, if you buy BP now, you can expect a nice return over the next couple of years. Liabilities, even in the worst case scenario, are not what were once feared.
