This information comes from Ken Toyoda, chief spokesman at Nintendo….
“We wanted to give the gaming industry a head’s up about what to expect from Nintendo at E3. We’ll invite people to play with the new device then.”
The 3DS being playable at E3 is a good sign that the device will launch sooner rather than later. This also answers some of the questions regarding why Nintendo decided to announce the handheld today rather than at their conference in June. Now the question is, what type of software will be on display at E3?
