in a nutshell (as far as I can follow the thread and discussion)- SC05 said that the announcement will come by October 7th, other sources said that announcement was to come "soon", people logically concluded that if an announcement comes it will be by mid-week (Tuesday- Wednesday) and another alleged source said to expect the announcement today. (however we also have conflicting sources that says the announcement will come 1-2 weeks later)
Therefore it comes to a game of "where's the announcement" and "what time is it at California"
In reality it's all unconfirmed news from sources and not certain. It may or may not happen today.
(btw it's the announcement of album release)
