I would also like to know the answer to this question... I was looking on the store last night to try and figure it out but couldn't see any high end configs that were available immediately in the UK.
Thanks, but that's not it. The ultimate configuration is not one of the default 3 shown on the site. It's typically got the 3rd tier upgrade of storage and RAM.
The unlisted configs were 64GB 2TB & 64GB 4TB last time with 2021 models.
Not sure if they will add 96GB since it is now possible, or if they will keep 64GB.
