nah I don't think GLORIA will overtake You were ... / BALLAD
GLORIA didn't had any tie in or so to pull in sales (I could be wrong though) as compared to her comeback single
again which was used to promote the fullmetal anime
It's all too much / Never say die's tie in's were decent as they served as promo songs for Kaiji the movie (which will open tomorrow here

)
then again , YUI's singles sales have been around 100K + or so
