Seriously, as if that record mean something, AKB hasn't done before doesn't mean they can't if they did try. It's just like MM's record for 50 singles in Top10 weekly.
(For me, it would mean something if they accomplished it w/o theatre HS event for both single and album.)
Even though I agree to some extent with what you are saying, a record is a record. No matter how lame it may be. All CD sales records are relative anyway, because of the time of release, sales gimmicks and whatnot... but still. They can set a record and let's just see if someone can actually break it.
The lack of handshake event wouldn't mean anything either, because nowadays pretty much every group has release events. From the most obscure idols to the biggest groups out there, they all do it.
Anyway, I think the idea is pretty funny and that's what it's all about: entertainment. (+staying in the news)
The album itself sounds exactly like I thought it would be; a lot of singles and some bonus stuff. The 63 solo PVs does sound interesting, but I highly doubt they got to choose their own songs, lol.
