No one seems to know for sure yet. If it's something concerning the concert, it must be some VTR or something, not a teaser since it's only 5 days away.
Talking about the concert, my friend just told me about some rumours that there'd be a bunch of guests. Like Onew (duet with Sica), Eunhyuk (dance with Yoona), Shindong, Leeteuk, f(x), etc. I don't know about you guys, but I'll be really pissed if this is true. I wanna see the girls' solo concert, not SM Town concert. It's a 2 hours concert with NINE of them. 9 is a lot. I'm sure they can deal with it themselves. Onew is okay though, since he has a song with Jess.
Also, new toys, collector's cards;

On #2, it says "SNSD's 2010 upcoming
mini album signed CDs."
WTF? I want a FULL album!
