I wouldn't say that necessarily - management games are certainly aimed at the hardcore - and so are almost all driving games - and those are certainly 'sports'. Sims is aimed at a very different market to a game like FIFA in any case - for one it's aimed also at that other gender I hear so much about.
FIFA, and PES are games which span the whole range. There are no football simulation games like there are driving sims like rFactor - so naturally the hardcore footy gamers are all going to be in FIFA/PES's paddock no matter what. FIFA and PES are more akin to a game like Gran Turismo than anything - they are realistic to a point - and they aim to be realistic to a point... but they also have to be conscious of the fact that the largest part of their fanbase is largely made up of casual football fans. The graphics will be pushed to the limit (not necessarily of the hardware but of the time constraints and financial constraints) of the console.
But the ultimate truth is that PC gaming is both dying - and to an extent has also been reborn. It's not quite what it was. There are few PC games which really go beyond what the best console games can do - certainly Gran Turismo 5, Uncharted 2, Killzone 2, and so forth are graphically monstrous and I'm not sure if even Crysis can push quite the same graphics. PC gaming survives in niches, primarily. Indepedent developers produce some great games - and strategy games still survive on the PC because they don't on the consoles. Shooters are in the balance - MW2 which was undoubtedly the most popular game of this generation (outside of given-away-for-free wii shovel ware) didn't even use dedicated servers.
The populations are steadily moving from one to the other, one genre after the next. The big hits are all on the console now aside from those hyper-hardcore simulation games, or games which still cannot come up with good enough control mechanisms for consoles (like strategy games). Crysis 2 is multiplatform. The Battlefield franchise is multiplatform. More and more games which are on PC and consoles will be LIKE console games on the PC - making modding hard, dedicated servers being rarer.
On the consoles, the hardcore population who wants sims will have to push to get them. It's happening, albeit it slowly. One of the biggest issues for console gaming is that because there is no modding community licensing becomes key. A development opportunity worth paying for the license is going to have to pull in a large number of sales to justify it - so a licensed game, which will be almost any driving/sports game which wants to be popular, will HAVE to take into account the casual gamers.
