Even the best kept secrets flow like water in the Western industry. Hell, the Xbox One had zebra striped consoles on a per developer basis to try and stop things and it did all of nothing. We have stories of Microsoft battering developers like that Crytek guy over the leaks as well, but it didn't seem to do anything either.
Ubisoft has a division dedicated to stopping leaks and I've even gotten complaints they sit around on this forum PMing people angrily and it's not like we don't hear about or see all of their games months if not years before their intended unveiling.
EA can't keep secrets. Activision can't keep secrets. Warner can't keep secrets. ZeniMax/Bethesda can't keep secrets. Even secrecy stalwarts like Blizzard and Rockstar have become leaky buckets over the years. If none of the people who are leaking their entire three year slates are saying anything about the system, who is working on the games?
The way things stay secret these days is that there's very few people working on them. One thing that does stay secret in the West is the existence of most indie games, but that's because there's 1-10 people sitting around making them. Sometimes smaller products like licensed games or children's products are the same.
If you could just ramp up an NDA and call it a day, everyone would have done so years ago.
While this is definitely true, I just can't be thinking of a scenario where NX, at launch, literally gets nothing from Western publishers (I'm talking about major publishers, not including indies). Again, at best I'm expecting a mediocre support right from the get go, with other support depending on first weeks both hardware and software sales.
Just to clarify: by "mediocre" support I mean several titles from Ubisoft, Activision and Warner Bros. (not just children-focused titles, but one-two of their core titles as well), both brand new games and late ports. Maybe (maybe - maybe - ) one-two titles from EA at launch and a Square Enix-Eidos side game. That's what I consider a mediocre support at launch from major Western publishers. So, my most optimistic prediction isn't that much to begin with, I'm expecting a bit less (no EA/Eidos, slightly titles from Activision/Ubisoft/Warner Bros.) seeing something a lot worse than that would be both surprising and depressing.
As Oregano noticed, we've yet to see a major hardware leak for NX, its physical appearance, while we had something for Wii U months before its first E3 showing (let's all remember Nintendo had two E3s where they showed Wii U). Also, John Harker already hinted at developers knowing about NX's hardware before E3 (while others at E3, as reported by Fortune). And, since next year 3DS turns 5 years old on February/March, I don't see a scenario where no NX at all is released in 2016 (by that, I mean that the handheld form factor should be out next year; I'm starting to expect both handheld and home form factors out next year, but let's stay cautious with predictions), thus I don't think a later-than-we-thought release explains the silence. I'm more on Vena's side on this: Nintendo is trying to control the message as much as possible. So far, we only had two official leaks about NX: DQX/XI from Square (literally read from the script during the event, then Square backtracked) and WSJ talking about SDK being distributed to developers (with the concurrent new Developer Page opening), and basically nothing else of that kind (just Tamaki's nebulous rumours or that thing from the Nintendo fansite, much more nebulous), unless we count several patents as leaks (but that's highly debatable).
Btw, here's the posts I was referring to in my former post
Theyre too busy dolling out NDAs
Is there an NDA for which NDAs they are dolling out?
Because if not, we'd be happy with such scraps.
hahaha. i think you can infer plenty though.

Nintendo's NDAs, even though they have gotten better in recent years, still feature a few loopholes. I believe they are updating the one for development now though, or have recently.
So, it seems Nintendo is reinforcing their NDAs strategy overall, starting from the Development Page itself (completely renewed and now modern, and featuring some policy changes). Now, does this mean we can start the whole "Wii U announcements are NDA, just wait and see!!111!" craze all over again (recalled by Y2Kev in the current NPD thread too :lol )? No way, absolutely no. Expecting major Western support for NX, especially at launch, is foolish. Even expecting mediocrity is optimistic (again), but I think this new NDA policy is preventing titles / development from being leaked, and they could be particularly efficient because there's not that much on the pipeline (less people involved), or (as you mentioned) titles being developed by smaller, less-budgeted branches (the smaller the team, the lower the chances of leaks coming out).
