Futuro perfecto continuó: will have been + verb-ing

La regla

Para enfatizar la duracion de una acción hasta un momento futuro.

"Emphasises duration of an action up to a future moment."

Se forma con will have been + verbo en -ing. Lo usamos cuando queremos destacar CUANTO TIEMPO algo ha estado sucediendo hasta un punto futuro. Marcadores: 'by + tiempo futuro' + 'for + duracion'. Diferencia con future perfect: ese se centra en completitud, este en duracion del proceso.
