"Chaos and confusion in the streets of the Middle-East is what would follow if any of the incumbent regimes of the Arab states were overthrown in a mass uprising". This is what most "middle-east experts and observers" had been warning since decades and especially in the last decade. Ironically, after the Egyptian #Jan25 revolution, it is these experts and diplomats who seem to be panicking now. So I wouldn't hazard a guess on which direction Arab politics would head once the dust has settled down in Tahrir. And of course, the ramifications are going to be huge and far reaching. However,t it wouldn't be difficult to realize that certain entities do face huge threat after the recent turn of events, Israel being the crucial and most visible one.
