I noticed that a lot of people seem to be scared of what’s going to happen at the end of the countdown. So I would just like to say that I doubt they would make a countdown if it was going to be a bad news.
I’m just speculating here but they might be using the time off to work on a new release. They might be looking for a new guitarist to take over Satoshi’s part. Akane also seems to be needing time to let his voice heal.
Whatever they are doing right now, my guess is that they are keeping it a secret to build up hype around the mystery. Those who have been following this band since the beginning might remember that they also had a similar countdown on their website a month or so prior to them officially starting activities (meanwhile they were recording their first maxi single and Akane underwent surgery on his vocal chords).
Also, I had the chance to talk to the members after the February 22nd’s live, and though they didn’t offer specific details about why they had no live scheduled beyond that point, they did tell us to “look forward”.
Sorry for the tl;dr but I hope this makes some of you feel better about the current state of things.
