Help with wp_query in wordpress

CMS & WordPress
1

on this page i have this code which pulls in the Upcoming Events:

<h2>Gold Coast Chamber Upcoming Events</h2>
Coming Soon...
<?php
  $loop = new WP_Query( array(
    'category_name' => 'Events',
    'orderby' => 'meta_value',
    'meta_key' => 'eventdate',
    'order' => ASC)
  );
  while ( $loop->have_posts() ) : $loop->the_post(); ?>
  <div class="sing-event">
    <p class="up-events"><a href="<?php the_permalink() ?>" title="<?php the_title_attribute(); ?>"><?php the_title(); ?></a></p>
    <div id="teaser"><img src="<?php $thumb = get_post_custom_values('teaser'); echo $thumb[0]; ?>" alt="<?php the_title(); ?>" /></div></div>
<?php endwhile; ?>

We don’t have any posts from that category at the moment so I inserted the text “Coming Soon…” but i’m wondering how I could fit that Coming Soon… into the code so that it gets auto-generated when there’s no posts in that category.

any idea? please advise. thanks in advance!
