The FUTURE PROGRESSIVE TENSE indicates continuing action, something that will be happening, going on, at some point in the future. This tense is formed with the modal "will" plus "be," plus the present participle of the verb (with an -ing ending): "I will be running in next year's Boston Marathon. Our campaign plans suggest that the President will be winning the southern vote by November. "

Generally, progressive forms occur only with what are called dynamic verbs and not with stative verbs. If you wish to review that concept now, click HERE.
