Do away with cells, bring better interface, and better graphics, and worry about accommodating primitive systems afterwards.
PC's update technology faster, have superior and more customizable interface, can use mods, and allow for more in-depth gameplay. It's fact. There's a reason Crysis wasn't a console game, and why Crysis 2 was so much crappier.
Accommodating dated consoles is dumb. Skyrim should have first been released PC only.
