Don't count your chickens before they are hatched, give SkyEurope a chance.
Anyway, I do not believe FR were keen to take NE over with its planes and debts. They might wait for a vacuum in CE Europe to fill it themselves. The airports (like Bratislava) having lost the important carrier are also more inclined to negotiate, passengers are searching the replacement for their routes... that's what Ryanair is certainly expecting.
