Something to think about if you're on the fence...
People are forgetting the second part of the 3DS redesign rumor - that Nintendo will be down playing the 3D, since so many people are worried about eye strain. None of the 3DS game HAVE to be played with 3D mode, so Nintendo could remove that option in the redesign. This would decrease production costs and increase battery life.
Obviously, this is just speculation, but it makes some sense. So, for me it's worth ~$110 for a system that I would enjoy now. Yeah, the 3D is a cheap trick that I'll most likely turn off for the majority of game play, but it is fun. I'm sure there will be a redesign at some point, but I also think the final design will fluctuate wildly depending on how the iPhone, Android, and Vita markets change.
End rant.
