I feel somewhat confident that Super Smash Bros will be released this fall, perhaps pushed back one or two months for a release in Nov/Dec, but it just can not be delayed any further than that. It's a title that must be released this fall, no matter what for Nintendo. So it will be.
As for Zelda U, well, yes it might actually be delayed until 2016 sad enough. :( Because they will be releasing Hyrule Warriors this fall, so a one year (in-between) the next Zelda installment I think would not bother Nintendo too much really. If they felt they needed to polish the game some extra, or add some more content to it.
What I am hoping for is SSB this fall, together with HW and then Zelda U next fall(Oct-Dec 2015). Achievable it is, but I do also think that Zelda U will be held back one year.
Another questions is, will HW be released this fall or actually Jan-April 2015? I think the game could be delayed too.
So many games are delayed these days. Too many games.
