Leebo and Web are exactly right.
Console gaming didn't become a billion-dollar business by catering to a niche. It caters to the masses, and the masses are comprised almost exclusively of casual players, of Madden Nation guys who think nothing of dropping back 30 yards and launching bombs. Think of Vince Vaughn playing NHL 95 in "Swingers" -- ROENICK!

-- and that's about 96.4 percent of your sports gaming population.
You're delusional if you think otherwise.
I think the crossing of the critical mass threshold by console gaming has created both a schism and a conundrum, especially for team sports gaming.
The schism is evident: Console team sports games are drifting more toward relaxed sims with arcadish bells and whistles. It's getting to the point that if you want as pure of a sim as the virtual world can produce in team sports games, you need to head to the PC and mod the sh*t out of the game with the great work done by the mod communities.
But that also creates a conundrum, as game companies -- especially EA -- are stopping production of PC sports games because they're not profitable. Why are they not profitable? Because no one buys them. And that's an even further indication that the hardcore community is WAY smaller than some think, because I don't know a person who plays PC sports games -- including me -- who doesn't mod the hell out of them to get even more realism.
Another conundrum is that the online sports gaming experience on PC's blows boxcar-sized chunks compared to that on consoles in terms of communication, ease of finding and creating games, avoiding mod conflicts, mismatches, etc. So even if you had a great PC game modded to perfection, it would be impossible to replicate the ease and features of Xbox Live in a PC environment.
My only current and probably future genre of sports gaming -- auto racing -- has featured this schism for years. If you want mass-market, fun, accessible, beer-and-pretzels racing games, you head to consoles. If you want as pure of a sim as this hobby can provide, you head to the PC.
Thankfully the conundrum isn't present in racing games, as the PC still remains somewhat fertile ground for racing game developers and modders. And rFactor's excellent online interface combined with Teamspeak is a halfway-decent poor man's replication of Live on the Xbox, not the 360. Good enough for me.
Still, with market pressures directing the video game industry more than ever, consoles will be the convenience store of video gaming while the PC will be the brewpub. If you want Budweiser or Miller Lite, go to the convenience store. If you want a regional craftbrew, go to the brewpub.
I'm no expert, but I do have the perspective of someone who was a hardcore console gaming as recently as three years ago who has shifted exclusively to PC.
Take care,
