What major stuff? It does 3D and has an analog nub? We kinda already knew that...
Where are specifics on the internals? The new online system? 3DSWare? Are we going to get WiiWare/VC on the 3DS? Pre-loaded software? (With the photo-editing software of the DSi and can't wait to see what they do for the 3D camera)What the hell is the purpose of the infrared? The final design? What kind of OS? Is there an app store? Is there VoIP? How much internal storage? How much are the new piracy measures going to affect the usability of the SD card slot? Is there rumble? Is the 3DS VC going to include classic GB/GBC/GBA games?
All they showed at E3 of the 3DS was the 3D screen works, the 3DS nub > PSP nub, and developers are lining up in major way behind it. The 3D cameras were an obvious inclusion, and they barely even mentioned them. While I was pleased with the lofty praise for the 3DS given by those lucky enough to experience it, I was quite disappointed by how little Nintendo actually told us about the system. They only showed us the obvious, I felt the E3 reveal was much like that first quick press release: just enough to keep us interested and talking, but little enough for them to adapt. I'm waiting to see the results of that adaptation, and am wondering when we will see it.
