That's very interesting and no your never late
if your curious!!
I don't think they should have called it Believe 2.0 perhaps
Believe in CW not all Believe material was on.
Emerald was supposed to be a surprise, so if they had called it Emerald they would had that tour then and in 2014. I think it didn't because every special on tour had at least 2 years. SFTH had 2, ANJ had 2, so Believe was on it's 2nd,
needed a 2nd year!. Emerald did 1 in 2014, but the Anniversary was like an Emerald year 2 in sense.
