Mashima wouldn't say anything about the new chapters. =( The people who got there last got all the free shit from the panel. =\ I saw him before the panel but i didn't recognize him.... Missed my chance to take a good picture of him ;_;
On the other hand, Mavis looks cuter than expected. I thought it was a fairy or something. I'd have expected Mavis to be some old dude.
And I agree, growth over 7 years would have been more interesting than them frozen in a time bubble. Over 7 years, they could have used that time to train and grow stronger motivated by their desire to next time be able to protect the guild should Acnologia attack again. Everyone getting a power up over 7 years would have been better.
