While this does confirm a rumor, it does sort of kill one as well, that being that a 3DS might be usable as a controller. Was that really a rumor though? Or, just something I started saying that a lot of people probably thought of as well. Maybe both. Anyways, the reason why I say that is because the rumor states six inch screen, while the 3DS' bottom screen (for 'tablet-style controls') is considerably less than that. So unless they could make it really tiny, the chance of that happening is pretty much nulled out as far as I can imagine. Such a lack of parity is a little saddening, but hopefully it'll be made up for elsewhere.
The article also states that the '2012' that Nintendo is shooting for means the latter half of '2012'. And December is definitely in the latter half of a year....
...Maybe the Mayans were right.
Something of a side-note here, there has been an absolute deluge of E3 news and the only company that's officially had a keynote is Konami. I am nowhere near capable of reporting half of it, let alone all of it, but I can direct you to someone who already has for the most part. So, Blam! Go to Chance's blog, take a look around and immerse yourself in the announcements, reveals, and trailers.
