I was really looking forward to these concerts, as was everyone else...
It was to be their biggest concerts in quite a while, and all the tickets sold out immediately. I'm an FC member and lost the ticket lottery to the evening concert, even... (I had to buy a ticket from a friend)
I don't mind at all though, and I hope Hitomi will get well soon!
The reason I said "cancel", is because they are apparently still going to let people into Akasaka Blitz on Sunday, but entry will be free (+ tickets refunded), and the 3 other members are planning some sort of free show.
Hitomi's lines will be played out through the speakers, since the other members don't have time to practice all of Hitomi's parts...
Good luck to TGS! (><)
