NG: As many of you know, just a few days ago I posted a story that confirmed that the specs of the Wii U dev kit that was leaked earlier last month were true. What maybe was not made clear enough in that post was that those specs were from a dev kit from late last year and some of the things were to change. It is nice though that we can at least confirm what developers were using at the time.
Now, some things have happened over the last few months while Nintendo has prepared the final dev kits to be mass produced for the Wii U. Back in March Nintendo signed a deal with Green Hills Software, the largest independent vendor of embedded software solutions. The Wii U will be using Green Hills Software's MULTI integrated development environment to maximum reliability, maximum performance, and minimum code size.
