We didn't get anything special on any other holiday. I think Ike's announcement was on a special day, but I don't remember what it was.
Anyway, we didn't get anything for Sakurai's Birthday, the old Release Date(Dec.3rd), Halloween, Thanksgiving. For Christmas we got a single Final Smash update (plus music, but whatever). Not only that, but it was a Final Smash we already knew, seen, and USED, albeit not all of us.
We got Sonic at the beginning of a convention, not a holiday.
New Years is not going to be any different. Don't just not get your hopes up, don't have any hope whatsoever. This is not even considering we haven't gotten anything substantial since the "Fox Misfortune" video back in November.
I'm not being a pessimist, just a realist.
