My post on it from the OT.
Regarding it being the best visuals by far this gen, based only on this tiny snippet, I'd have to strongly disagree. Imo there are a few other games that do snowy environments far more convincingly, with more realistic snow deformation, effects and granularity, as well as more detail and scope in the environments themselves. That said, these other games aren't 60fps so it's not exactly a fair comparison, though saying that we don't yet know the scale of Gears 5's environments either, so that factors in too.
