Post type specific upload folder in 3.5

Yes, it does. I had to do something similar just yesterday and worked out this solution. About the same as the linked solution, but with a bit more error checking.

<?php
add_filter('upload_dir', 'cgg_upload_dir');
function cgg_upload_dir($dir)
{
    // xxx Lots of $_REQUEST usage in here, not a great idea.

    // Are we where we want to be?
    if (!isset($_REQUEST['action']) || 'upload-attachment' !== $_REQUEST['action']) {
        return $dir;
    }

    // make sure we have a post ID
    if (!isset($_REQUEST['post_id'])) {
        return $dir;
    }

    // modify the path and url.
    $type = get_post_type($_REQUEST['post_id']);
    $uploads = apply_filters("{$type}_upload_directory", $type);
    $dir['path'] = path_join($dir['basedir'], $uploads);
    $dir['url'] = path_join($dir['baseurl'], $uploads);

    return $dir;
}
