Yep, can't wait. I wonder if it'll be the flute or a movie giveaway.

has anyone ever gotten anything from mystery gift

Member's Card, but that's it. The secret key was available a while ago.

chances are probably a movie giveaway before the flute
since in japan they gave away a lvl100 arceus with the signiture moves of giratina,palkia,dialga for seeing the movie and a special pichu for preordering tickets to the movie or something

i got both the key and the member card

and theyll give us the flute... we dont live in japan there wont be some wireless stuff at the movie.. tho i might have to go if there is

the movies are released straight to dvd here (i think) and places like toys r us hold the event that was held at the theatres in japan
idk about the pichu though, but if we don't get it we completely miss out on 1 in game event in HG/SS (untradeable via gts)
also that movie arceus (it's also untradeable on gts) activates an event as well in hg/ss that gets you either girtina/palkia/dialga at level 1 holding there respective orb and chances are we'll get it just like we got the regigas event from the last movie
