Well here the same stores are not always open on Thanksgiving. The mall last year I think was the first year closed for Thanksgiving (it may have 2015 can't remember if it was then or just last year). Only the anchor stores were allowed to be open (Dillards, Macys, Nordstrom and JCP).
Game Stop started being closed on Thanksgiving in 2015.
R.E.I started closing on Thanksgiving in 2015 though to be fair they also decided to forgo Black Friday in 2015 period.
I wouldn't expect the places to be busy during the after midnight range. I mean even when sales were at midnight places weren't busy busy busy at 3 am. We had been going to JCP at around 6:30am actually on Black Friday and it was dead...but that was part of the reason we went at that time. You can't be every place at the same time so places should typically see a rush then a slow down as the people from the rush have left and those who have been at other places now go to that place. I do think stores reevaluate if profitability-wise it makes sense to stay open at 3am, at 4am, at 5am rather than just close and reopen. I'm guessing though that employee-wise there are people who likely need to be there to clean up from Thanksgiving to get ready for Black Friday reopening though how long those employee's shifts are I would have no idea.
This year Nebraska Furniture Mart was open at 8am on actual Black Friday....last year it was 6am. They are however closed on Thanksgiving.
Some stores still push the envelope though like JCP that opened at 2pm who didn't used to be open for Thanksgiving just 5 or so years ago.
Most Best Buys this year should have been opened from 5pm Thanksgiving until 1am on Black Friday though most would reopen at 8am on Black Friday so it looks like your local Best Buy had the same hours as most around the country with the exception of shifting one hour. I don't know if my local Best Buys did what most around the country did or if they had different hours.
