Working code :)

I should use this code (this will also ignore the sticky posts):

<ul>
    <?php
    $args = array(
     'post_status' => 'future',
     'ignore_sticky_posts'    => true,
     'posts_per_page' => 5,
     'order' => 'DESC'
    );
    $my_query = new WP_Query($args);
    if ($my_query->have_posts()) {
        while ($my_query->have_posts()) : $my_query->the_post();

            $do_not_duplicate = $post->ID; ?>
            <li> <?php the_title(); ?>
            <span class="post-date">Expected: <?php echo get_the_date('Y-m-d');?></span>
            </li>
        <?php endwhile;
    }
    ?>
    </ul>
