It's not going to be released out of office hours... Like I said previously, actual software engineers release it literally when they have arrived at work, usually after 9am. They will do it, from what I have experienced, on a mid week day such as a Tuesday, Wednesday or Thursday so that the engineers are on hand if anything goes wrong such as mass bootloops and crashes so they can work on fixes and monitor progress.
No, just don't have the same level of dealing with buffoons as others do, in this case you the "troll" have appeared and caught my attention.
If people are really wanting the update and are getting frustrated or annoyed leave them to it you coming and trolling people is quite a child like thing to do.
Just learn to grow up and show some respect.
I've just gone through the whole list of XEU (UK and Ireland) firmwares and looked at the release dates... They all seem to be a Wednesday or a thursday
Take a look for yourself
I reckon BTU will be much the same
Edit: just had a look at BTU release history and saw only 2 releases come out on a Monday and Friday... The rest were either Wednesday or Thursday
They all seem to hit the Samsung servers in the morning... So this week I would say looks good for a release!
