Nope, got to respect the consolers, they are our bread and butter.(you guys still can't have mods though, sorry.)
I don't mind the game being PORTED to the consoles, but don't dumb the game down just so they can release it at the same time as the PC version. I say make a PC version for PCs, and a console version for consoles a few months or so later. Change the interface and menu screens, resolutions, etc. I own both the PC versions of Morrowind and the Xbox version and it worked out perfectly fine for both. The PC version did not feel like a cheap port by using new menus and interfaces, as well as improved graphical options and performance, while allowing Xbox users to play the same game with slightly inferior graphics and a interface designed for them.
As for the size of the world, Oblivion was good for it's day, but it's been 5 years since then and the quality and quantity of the game should reflect that. Making Skyrim the same size as Oblivion would only make Skyrim size "meh" instead of the "awesome" reaction i had with Oblivion.
