Some Nintendo 3DS rumors are kicking around this morning, compliments of a report from Bloomberg that the company is holding a pre-Tokyo Game Show event on September 13 that is related to the newly released handheld. This is unusual, as Nintendo does not usually have a presence at TGS.
Bloomberg offers no details, but Inside Games (via Andrisang) brings word that Nintendo company plans to announce "an extremely big title" sometime soon. It should be noted too that the source doesn't link this announcement with the September 13 event, though it's certainly a likely platform for such a reveal.
Meanwhile, a report from French website 01net (via CVG) brings word from an unnamed source that a hardware redesign is in the works for the 3DS. The source suggests that the new device will sport a new name, with a "radically tone[d] down" 3D effect and a second analog input. Nintendo is also reportedly working on a low-cost attachment that would bring a second analog control to current 3DS models.
No connections are made between these rumors and Bloomberg's report of a pre-TGS event in any of the write-ups. I think most would agree that it would be a mistake to announce a hardware redesign now, as early adopters are still smarting after this month's 3DS price drop. A new game announcement seems much more likely, or perhaps a confirmation of release dates on some of the platform's more highly anticipated upcoming games.
