There are much more differentiating factors between those 2 versions of a game then just one has better graphics and one doesn't. They are totally different forms of gaming. First of all, much less people have a PC capable enough to run the game at this "undeniably superior" level, while that's not a worry for consoles.
Come on I can't even believe I have to say the difference between the two. You simply and positively cannot be comparing 3rd party releases between console vs PC and console vs console. Console vs Console is as basic as it gets. They're both machines with built in specs, they're both played the same way, they're both played on the same couch, they're both played in the same room, they both sit in the same box place under your tv.
Choosing to buy a console game over another console game is as basic as things get. Are the graphics better? Is the online better? Simple questions like that. Wii-U will have an easier time getting support, that only solves half the problem, the other half is having the support mean something with sales. I could be wrong, I'll say that again. But as it stands, common sense would have you know that core gamers would choose the console with better graphics/better online/better whatever else, over the inferior one.
PC vs Console, like I mentioned above, has much more factors that come into play. A lot of people just don't have the graphics capabilities in their PCs, they aren't comfortable gaming on their computers because it isn't something they do often (because they're busy buying lots of console games most of the time), and so on and so forth. It's just easier/more convenient to get a console game over a PC game, in terms of thought process that goes along with it. It's not as simple as PC is a much stronger and superior gaming experience. Is it? My PC won't be able to run BF3 THAT well so I'm getting it for PS3 first, because I can't take advantage of anything the PC has to offer, that and I enjoy playing on consoles more with all my friends that also have a console that can play the game without worrying about graphics cards/drivers/DRM, digital vs not, etc...the whole PC package.
Not a knock on the master race, they are comfortable with all of that, but lets not delude ourselves into thinking that it's just as easy to get into PC gaming than console gaming.
edit: and I'll say it again, to the dude that quoted me above, I'm OPENLY conceding I could be wrong, there are LOTS of asterisks in my assumptions, it's all based on the final version of the console, it's based on 720/ps4, it's based on game engines, and so on. I'm just working on what I have now, and that is assumptions that aren't THAT crazy.
