Hey acrylian, I just noticed that your zenpage-default news.php code may have a bug in which the latest article posted would not display the next article link. Let me know if I'm wrong.

// single news article
if(is_NewsArticle()) {
?>

should be changed to:

// single news article
if(is_NewsArticle()) {
?>

Thanks! I already noticed that, fix will be in the svn today.
