No I don't see it, Nintendo has to sell amiibo toys this holiday.
They will ship Smash with missing characters/stages and introduce those as free DLC if need be rather than delaying the game. That would be too drastic of a measure to take.
Zelda being move into 2016 is a bit of a different story because Nintendo may want it as a dual release to launch their next handheld with (could be around this time), so there's motivation to do so there, there's no gain for Nintendo delaying Smash out of this holiday window.
