and four years ago 8GB of RAM was the standard for a gaming PC, with about 1GB of VRAM.. these days, most gaming PCs have a minimal of 12GB of RAM (although, 16GB is becoming very common at this point), plus at least 2GB of VRAM..
my point being, alot of the resource intensive mods (which are usually the popular ones) just won't work on Consoles, unless they try and keep the system specs close to Skyrims (but judging by the footage we've seen so far, that won't happen)
EDIT: Not trying to bad talk consoles or anything, i love my consoles just as much as i love my computers, just stating the facts as they stand
