What do you mean by "officially confirmed"? You later posted that this won't be announced or confirmed on the internet for two weeks, but it was confirmed by "Universal itself" -- what does this mean? There's nothing new on the TM webpage, or in the Universal News that TMs read, and no one has found a news article confirming this yet (on or off the internet). If this is insider information, you might want to be careful -- Universal reads this forum and has put a gag on those who give away their secrets.
If this Holiday Feast is none of the above (in other words, make-believe), please don't post speculations, ideas, hopes, dreams, or HP fantasies of your own as truth without indicating that it's really just your own idea, and you hope it comes true. There was a SASsy individual who did this in the past, and he messed some people's plans and predictions, wasting quite a lot of time. I'm not saying you're making this up, because I don't truly know - but the evidence is not on your side so far.
---- UPDATE -----
I am basing this on your recent post: please don't play tricks that "all of you idiots"will fall for. There are probably other forums where that is perfectly okay, and I encourage that behavior there. But not here. Thank you.
