Well, these estimates are always off, so I'm taking the info with a grain of salt or two. But even still, if it is true, one of the things I ALWAYS count on with a Nintendo handheld is that the battery life will be fantastic, and this is making me a little wary. I didn't buy a PSP until they increased the battery life, and if there are similar limitations on a 3DS I might have a reason to delay picking one up.
Ever since Nintendo hit it off with the Wii and the DS, it feels like they're getting arrogant. But maybe it's just me.
