Talk:Russian/Grammar/Future tense

Perfective verbs not allowed with a stated duration
The article currently says that in the future tense, only perfective verbs can be used with a stated duration. Every other resource I've come across says that only IMperfective verbs can be used with a stated duration, regardless of tense. I haven't been able to find a single resource that agrees with the article on this point. Could someone, preferably a native Russian speaker, please confirm this one way or the other? Thanks!
