Thoughts For Twenty Twelve Theme

Hi all,

Had anyone notice the coming Twenty Twelve Theme? The theme is developed using Toolbox theme. I notice something different in the header.php. Something coded like this:

<?php
if ( is_singular() && comments_open() && get_option( 'thread_comments' ) )
wp_enqueue_script( 'comment-reply' );

wp_enqueue_style( 'fonts', 'http://fonts.googleapis.com/css?family=Open+Sans:300italic,400italic,600italic,700italic,400,300,600,700' );

wp_enqueue_style( 'twentytwelve-style', get_stylesheet_uri() );
?>

Any thought, anyone?
