Oh well.....my pre-order of Super Mario 3D All-stars canceled and I was one of the first buyers there. I ordered the game September 4th. Anyway, here it is the official response by Base UK and I have underlined something interesting.
"We have just been notified of our allocation of Super Mario 3D All-stars (Nintendo Switch) and it is woefully short. This is very disappointing and it is with great regret that we have to inform you that we will be unable to fulfil you order on the day of release. Further, as Nintendo and their UK distributers are unable to give us any reassurance that more stock will become available after release, we have taken the regrettable decision to cancel all orders. "
