...that's still alo-hello dvd and not at all the version they used to promote the single, so? MM dance in their genki pikappika video, too.
My personal position on that is that anyway - alo-hello is completely FOR the fans, and if it's for the fans (much like photobooks) that's one thing. If it's something that's gonna play on whatever music channel and/or rankings? A whole different thing as that will reach many, many people who aren't necessarily a fan of the group but will create an image of it from the few seconds they see.
Which, if the actual PVs would be bikini would be... well. How people react/ed to AKB. Some love it, some really don't.
