The stripping of cite from the <blockquote> tag will be fixed with the 
next TinyMCE update. If can be fixed now by specifying:

'extended_valid_elements' => 'blockquote[cite]',

in the init array in tiny_mce_config.php, or by making a really simple 
plugin:

function fix_cite($args) {
   $args['extended_valid_elements'] = 'blockquote[cite]';
   return $args;
)
add_filter( 'tiny_mce_before_init', 'fix_cite' );
