Well, i think a fair way to give an opinion of what happened today is saying peacefully (and im not pointing on someone, im just saying on reactions on their stream chat or social media).
Like i said before, i know hat they usually this cryptic stuff to announce new music or something like that, its fair, its ok. This particulary time, in where they were inactive this last 7 years for reasons we already know, i think that could be the exception one that we get the reveal today (or at least some extra info, not saying "we have a new singer" or "we have a new song coming", but something extra to be even more excited).
That said, like i said on the end of the last sentence, despite that im excited, i know that i will not be the same, but im here to see what happens and how it works. So much people is thinking what could happen after they announce whatever they have to announce, and i think that if they took 7 years to come back (apart from the time they needed), it was because they got something that they think it will work great.
