While it would make sense to do a great update on specifically that day, I don't think Sakurai will do that.
Everyone who got their hopes up for Dec. 3rd, I'm sorry, but America is certainly not the only country in the world. Your fault for believing in a silly "prediction" and thus being disappointed about it. Halloween...it's more of an American holiday, though other countries know about it too, they just don't celebrate it the same way and is by far not the most special day in Octobre. Now, Thanksgiving...I don't know about you, but I guess this we all can agree was absolutely stupid to believe in a super duper update. I mean, it speaks for itself. Then on all the birthdays, there wasn't a great update as many had hoped.
So, Christmas is a little bit different, and I'm sure Sakurai knows about the holiday as do many people in the world, but once again, you can't be sure. So let's keep it down, please, for the sake of this community
And I DON'T agree that the updates, in comparison to these major days, weren't that good. Today is a normal day, and STILL there was a very good double update, a stage AND music.
