If you pre-order ps5, will you get it earlier before release day or on release day?
On release day, of course.
But only if you are lucky, this can happen due to delivery bottlenecks at DHL / DPD and co. Still change.
No, you only get it on the release day, if at all. Every retailer who gives out earlier is liable to prosecution if it comes out and has to pay a lot of fine and no one will take that on themselves (I work in retail myself, so I know that because we have these discussions with every release, whether console or Game)
On delivery date, when else.
If you have it delivered to you, there's a good chance it will arrive a day earlier. With a lot of luck, two days too, but unlikely.
Provided that delivery can generally be made on time, of course.
