It's worth noting that Aonuma didn't confirm a 2016 release date for the new Zelda.
Well, what you said isn't actually fact. Seeing as you -
1). don't work for Nintendo
2). don't have access to Aonuma
3). don't know what's involved in putting together an E3 demo
- you're really just speculating like the rest of us.
It's true that 2016 was never confirmed, but seeing how the game would arrive later this year and the delay still happened. I think it's safe to say it's really delayed to 2016.
My guess is that if they were confident on them being able to get the game out in time of BF or Christmas, then no video would have been shown.
If past Zeldas are any indication, then the game really is being delayed... and by a long time!
Personally, i think that if the game isn't out, at least, until 2016's 2Q, then you can bet they will save it for Christmas 2016- thus increasing the chances of being ported to whatever NX is.
Not having a demo is not really the problem. It's the fact that the game won't even make an appearance at E3. Not even a video like the one showed at TGS in December.
That can't take that much time to put together... which makes me believe that the change will be relevant and not superficial - leading to a big delay instead of a small delay of a few months.
