Along with the unveiling of Wii U at E3, Nintendo subsequently revealed further details regarding the technical specifications of the console. There is, however, plenty we still don't know about Wii U and with a scheduled launch in 2012, we can expect these unknowns to be revealed slowly like a season of Lost.
A couple of things that Nintendo's fact sheet didn't cover have thankfully been clarified and it appears to be a mixture of good and bad news. Firstly, Nintendo EAD designer Katsuya Eguchi confirmed that the Wii U discs will indeed hold a capacity of 25GB, as rumoured early last month. This, of course, is a significant increase from the 4.5GB single-layer DVDs that the Wii uses, as well as the dual-layer DVD9 discs which hold 9GB, used by the Wii and the Xbox 360. 25GB is on par with single-layer Blu-ray Discs that the PlayStation 3 uses, and Nintendo's decision to once again use a proprietary format is likely an effort to clamp down on piracy.
Wii U clearly uses a disc format that's much more in line with contemporary standards, but Nintendo is also looking back as much as it is looking forward. Well, back as far as the Wii, at least. Wii games will be compatible with the Wii U, along with all the peripheral hardware like Wii Remotes, Wii Balance Boards, etc. However, speaking to Kotaku, Nintendo of America president Reggie Fils-Aime revealed that GameCube games will not be playable on Wii U. Like the removal of the Game Boy Advance slot on the DSi and subsequently the 3DS, it seems Nintendo is drawing a line regarding how far back it is willing to provide backwards compatibility.
Does this mean we'll one day see a Virtual Console on the Wii U with GameCube games to choose from? Let us know if you think that would be a good idea or not and why.
