Information about SZ's debut single information has been updated on Johnny's net which includes a more detailed version of what's on two of the DVDs plus titles for the other two B-sides.
The 1st version is still only the PV for the titled track. The 2nd version goes on to explain the close up version thing a bit. There are five different versions, one for each boy, and this will be a close up shot for the PV. I'm honestly assuming that this is pretty much the same thing as the hidden PV alternate angles on Hey! Say! 7's Hey! Say! single were, which for those trying to figure out who sings what part will be a big help for. Then for the 3rd and final version with a DVD it is the making of for the PV. It also has footage of from the jacket shooting and the boys each give an introduction of themselves. The total time for this DVD will be 39 minutes.
Moving on the the other two CDs without DVDs do both have the titles for each of their B-sides. The one that comes with the photo book will have a B-side titled Knock! Knock!! Knock!!! and the RE has a B-side titled I see the light ~Bokutachi no Suteejii~ (I see the light ~Our Stage~).
I'm going to guess that we probably won't have to wait too much longer before we get the previews for the covers seeing as we're less than a month away from the release. If we don't get them in the next couple of days by next for sure as that's when the boys will start appearing on programs and I'm sure they'll want to show a cover of the CD so people know what to look for in stores when it comes out.
