From the news, the new model of the PS5, although not referred to as the PS5 Slim, has added additional details regarding its stand. These details are as follows:
The vertical stand, which was included in the original model, now requires an additional purchase of a new stand for $29.99.
The horizontal stand from the original model can still be used in both orientations. However, since the new model does not come with a full-sized stand, it includes a “small-sized stand” for supporting the console horizontally (which may seem a bit peculiar).
The new model of the PS5 still utilizes the same chipset as the previous one, but it slightly increases the storage capacity from 825GB to 1TB and reduces the size of the console by 30%. Additionally, it allows for the removal of the hard drive.
TLDR: The new PS5 model features a more complex stand design and requires the purchase of a separate stand for vertical orientation. It also offers increased storage and a smaller overall size, while still using the same chipset.
