Does anyone think Roger Federer will actually regain the #1 spot ever again ?

Great news for us Rafa fans :) Nadal has secured the #1 ranking, Roger cant overtake him :P Anyway do you reckon Federer will ever be back at #1? Theres sooo many young and upcoming players on tour now its going to be even harder for Federer, he no longer just has Nadal breathing down his neck or Djokovic. Opinions please :)
