I hope they add some graphical updates like raytracing in pc and ps5 pro. I still hope for big expansion just like the size of Lies of P expansion or Elden ring shadow of the erd tree. There is so much lore and characters that need sidestory and there are also potential hidden levels and areas in SB.
I also saw it, the grassy area, but I m not sure, I think that's from the game Nikke. I will be happy too see new locations and levels and new sidestory. I like the new costumes but I hope for more content in the dlc.
If it's getting well over 120 fps without DLSS at all, you're going to be starting from such a high frame rate with it enabled that will next to no impact on your experience.
At the same time, if you are already getting 120 fps, I don't know why you'd bother with frame gen anyway. The tech always seems the most useful when you need it the least, which is why I never use it.
