So you know when the cover was released? 4 days after that the behind the scenes was revealed. Maybe 4 days after that there will be a new update! (on friday)

Could this be possible?

not really too much evidence in that pattern for it to be considered one

You need more that two data points to establish a trend. I expect we'll see at least one piece of info per week until the end of the month. Maybe as many as two or three updates in a single week. I think it's likely that we hear something new before this weekend, but that's pure speculation.
