The trend is usually on Friday, but you could launch it any day of the week. For example, Limitless was released on a Thursday. The first single from the new Metallica album was released on a Monday.

Next Friday is 31st, so... it might as well be released. But I have a feeling it won't happen until April. Usually there should be some pre-post before launch, an announcement on their social networks at least.

Crossing fingers.
