Fabian has backed up his statements on NX on his Twitter: http://m.neogaf.com/showpost.php?p=207803000
*Fabian Doehla was not joking when he referred to hearing devs being very excited for the NX, he works for CD Projekt Red and Sega, so whatever developers know, he is likely aware. Fabian also leaked the original Xbox in 2000 by accident, so those claiming he doesn't know anything are being presumptuous.
Interview about NX starts about the 7 minute mark below:
Here is the translation:
Host: What do you know about NX?
Fabian: It will be fantastic. As developer [CD Projekt] you get access to the hardware and everybody [at CD Projekt] is looking forward. We know things.
Host: Are you lying now?
Fabian: No, no.
Host: Sometimes I cannot tell if you are telling the truth or not.
Fabian: No, no! It was like this in the past as the Wii prototypes came in, back then called “Revolution”. It was so funny that in Japan they were all very excited at the developer studios of SEGA, they thought it was very good. The Europeans took a little longer. Like “Well, maybe this doesn’t work”, you know, because it was technically just a GameCube. It was not much more. But NX what you hear [of the developers] about NX is all very positive.
Host: But the hardware will be much worse than the new Xbox.
Fabian: I think this will never again be the main emphasis in the future [for Nintendo]. Can it [NX] be better than the new Xbox? Take a realistic point of view: is Nintendo able to build a console that has got more power than Xbox?
Host: In theory it is possible.
Fabian: Affordable? Do they have the contacts to the industrial facilities, resources… [Shakes head several times in denial] And what would be the positive outcome? Who is going to develop games for it?
*They go on to talk about SNES, 32X, Dreamcast etc*……Fabian: But anyway, I am really looking forward to NX.
Host: I see. But what kind of console will it be? Will it be a handheld? Or…
Fabian: It will be spectacular!
Host: *Jokingly* Nah, you know nothing. I’ll have a look in the chat.
Fabian: I’ll not make the mistake to reveal a console again. Not at this time.
Host: But if – please in my show.
Fabian: If yes than with you tonight in your pool. [Talking about the pool and some private stuff. The Interview moves on in a different direction.]
