I think they speak English well, and have gotten better at singing it. (For oblivious for example, in the recording it still sounds Japanese-ish, but the more recent lives, she sings is pretty well, with the L sound more dominant. Since their L's are almost always R's in Japanese.) So back then they would have sung Believe Berievu, but now I think they will pronounce it right... though, heavenly blue was still bruuu. lol Anyways, I think they can still have English phrases in the songs, and that will be enough, since I know most of their songs by heart while singing with them, since I listened to them a million times, even though I don't know Japanese. :P (But I think Yuuka must have had a hard time with Cazador, though maybe she studied Spanish, not sure. I think it's more likely for the Japanese to study English.)
I want to see new dresses! And yeah, it's less than a month till we hear the tv size, which I am excited for. So I guess if we don't hear a sample of it before then I won't be mad, I will be happy since I want to be surprised.
