Anyway, it seems like it just aired on Japanese TV with a completely different opening: http://www.youtube.com/watch?v=7WSh3yMjv9k&hd=1
From what the comments in the youtube channel say, very spoilerish. It almost seems like this should have been the opening for the second half of the series and they just now finished it, so they decided to tack it on the TV broadcast.
Yeah, that seems like it would have been an OP 2 but they forgot to put it in. Well, it's not like it's not a bad song or anything. Boom Boom Satellites are an awesome band. And at the very least, the scenes flow together quite nicely with the music (It's always cool to see Raigyo in Xam'd form)
I agree it was spoilerific and that this could have been used for the second half. But, it was good. Plus, it still has Boom Boom Satellites, and a new single to boot! (It won't be out until July 1)
The new OP really drives the E7 similiarities home. On the plus side, it's nice to hear a J-Rock song that I can actually almost 100% understand (guess the vocalist took an English class).
Absolutely love the song, but the OP is VERY spoilerific. I suppose it's not a huge problem though, as there's plenty of Opening/Endings that are spoilerific out there.
