My only concern about SSD (which is great btw) is actual size, while they will get them cheap at cost for the parts, 2TB SSD isn't cheap. If it comes with 1 TB, well, my 1TB SSHD is mostly full most the time.
User interface improvements are the most important for me, speed of navigating the menus, customisation and stuff is always welcome. I expect the console to basically just be a revamped specs in reality because that's all we really need.
What is ray-tracing?
Hmm, pie.
