First of all I really wanted the digital edition, mostly because it looks nicer to me and I never use discs. Also I really don't want to miss out on playing on launch day.
So...
I pre-ordered a 'PS5' back in Jan, but didn't receive any confirmation prior to when others were selling, so felt the need to secure 1. Also this retailer didn't communicate how/if I would get to choose between digital and disc (so far looks like disc).
So at midnight some UK retailers started to sell, the only one I could get was a DIsc based one. But thought at least this has been confirmed, so was a good backup. They also allow in-store pick up on launch day, so I know at least it will be playable on the day.
Then I saw another retailer were selling Digital editions the following morning (was about 6:30 am) so immediately snatched one. I have never used this retailer for console launch day purchases so have no idea if it will actually arrive that day.
Finally at 9am that morning Amazon listed the Digital and I managed to get one, and all the accessories I need/want. I'm pretty confident they will deliver.
So as it stands I have 3 (maybe 4). But I only want to keep 1. I will likely cancel the 2 disc versions and keep the other 2 digital editions. Whichever comes first I will keep and use, the other I will sell to a friend (at face value).
