The worst part of the new display is that the stand is integrated - you cannot change your mind after you buy it. So if you buy a fancy monitor arm a year after you got your Studio Display with a height-adjustable stand, you'll have to buy a new Studio Display, except this time with a VESA mount.

If you insist on getting a Studio Display, the best option to future-proof your purchase is to get the one with the VESA mount, because at least that way you can have a free choice of stands/arms.
