IWhat to watch for

The future of creer adds the endings to the whole infinitive, so the double e stays: creeré, creerás, creerá, creeremos, creeréis, creerán. There is no spelling change here — the y of creyó only appears in the preterite.

The future of creer typically predicts reactions: nadie te creerá, cuando lo veas lo creerás, mis padres nunca lo creerán. No lo creerás, pero… is also a set phrase for announcing surprising news.
