Update:
Earlier today, Japanese financial paper Nikkei reported on new developments at Nintendo.  These included a larger 3DS, a price point for the Wii U, and various non-gaming features of the Wii U console.

Nintendo has now denied this report on their official Japanese website.

Andrisang (our translation source for the original Nikkei article) reports that “Nintendo’s statement claims that the Nikkei report is not based off things announced by Nintendo, is full of mistakes and is nothing more than conjecture from the paper’s publisher.”

Original Article:
Japanese financial paper Nikkei has reported on various new developments from Nintendo.

First up, they are reporting a larger 3DS iteration, akin to the DSi XL, with a 4.3 inch screen.  A release across all major regions is suspected as early as summer.

Also being reported is a potential 30,000 JPY (Japanese Yen) price point for the upcoming Wii U console.  Converted, that comes out to $382.94 USD (US Dollar), 306.75 EUR (Euro), and 249.10 GBP (British Pound).  If true, a price point between $350-400 seems likely for the US release, though Nintendo had previously stated that they would not be revealing the price point of the Wii U at this year’s E3 event.

Non-gaming content for the Wii-U console was also discussed, including books, a large karaoke selection, and even car navigation.

Nintendo’s E3 2012 press conference kicks off this Tuesday, June 5^th, at 9am PDT.
