Here are some screen shots from Goseiger Episode 45. As the series begins it's final phase, nearing the end, Buredoran has finally revealed his true self. He is now known as Kyuuseishu no Burajira, which I believe translates as Burajira of the Messiah. (Or "Savior". TV-Nihon translated Kyuuseishu as Savior, and Wikipedia translates it as Messiah. I think both apply.) I am very excited for this, as it's the final culmination of a year's worth of mystery and guessing.
Also of note - I recieved my copy of the final Goseiger Music CD set. You can try and find it, named "Goseiger Zenkyokushu" (Zenkyokushu essentially means Final CD Collection. Look for that word when trying to find a series' final Music Collection) The title on the CD, though, is "Goseiger Super Songs Dynamic!"
It's a good collection, with a lot of good songs. They do add a lot of Karaoke versions of the various songs, and also have quite a few versions of Gotcha☆Goseiger (the closing theme) - but over all there are probably 15 individual songs it offers. No separate songs for each Goseiger member, though. Still a definite good buy!
You can find it on sale here: CDJapan. Usually I buy CDs at Play-Asia, as they typically have a slightly lower price. But CDJapan was the only one listing this CD set.
