Congrats, being on here should help the wait
It might turn up a bit earlier, you never know, unless there's a supply/production issue it's usually around 8 weeks I think.
At least you got the Business speaker upgrade: there's a smaller difference between business>HK than standard>business, so you've still got a good sound system. The wait will seem long at the time, but it all all be a distant memory come delivery day!
