I don't know what will happen in the 
future, but I'll promise one thing!
،لا أدري ما الّذي سيحدث في المستقبل
!لكنّي أعدكم بشيء واحد
Wir wissen nicht, was die Zukunft bringen wird,
aber eines versprechen wir!
No sé lo que pasará en el futuro,
pero les prometemos algo.
No sé lo que pasará en el futuro,
pero os prometemos algo.
On sait pas où ça nous mènera,
Non so cosa succederà in futuro, 
ma una cosa possiamo promettervela!
Não sei o que acontecerá no 
futuro, mas prometemos uma coisa!
Не знаю, что ждёт нас впереди, 
но одно вам обещаем!
