It looks like they changed the intro a bit, with new clips of new enemies, new friends, Dai-Gurren and Nia and no Kamina =(. Anyways, with the addition of Nia I hope Simon doesn't drop his thing for Yoko. It might turn out that way because Yoko is so obsessed and in love with Kamina, and Nia's around the same age/height (though a little taller) as Simon so it seems more of a match.
