At the same time, while I do definitely agree with most of the post
@AH49 (You seem to have done your homework instead of going about it half cocked like some on this forum do when it comes to the broader bit of business and racing games) you have to realize the contraction of the racing genre also can be attributed to the death of the A and AA developers and studio houses, and subsequently, indie developers having the lack of resources to pick up the slack. The era of Tokyo Xtreme Racer, Juiced, and etc from smaller publishers like Genki, THQ and others is gone. And indie developers simply cannot bear the load, especially when it comes to time, engine restraints, and most importantly, licensing agreements. If you are using real cars for example, like in the case of the two series I mentioned above, if you are even Chevy or Ford, manufacturers who almost always are pretty open with licensing agreements, why would you give your money to a bunch of kids making a racing game in their spare time?
To your point about the trends pointing towards what GT Sport has become, well yeah, it might be right from a business perspective, but what has been argued about, certainly by me, and others here in the forum is whether or not it will *actually* translate. The only other game that comes close to the way that GT Sport is going about this is iRacing, and while it might be successful enough to survive to this point, it helps that it is consistently hooking people for their money with subscription rates.
And here is the main issue: that very embracing of online and social features. I have said this many times before, but public sim racing lobbies, more often then not, are gong shows. From what I have seen of beta clips, a pithy little driver rating and ghosting opponents isn't going to do jack, and that's exacerbated by the fact that with the lack of career mode content, people are just probably going to ditch the game and not even bother with the online aside from surface level cursory glances.
Really, the decision to focus on online and esports exclusively and offer this lackluster content for single player just really reeks of Polyphony throwing the baby out with the bathwater. Really, they didn't need to focus on those two aspects exclusively, they could have just tried to once again fix the career mode using its competition to try and figure out where to do better, but if that's what Polyphony wants to do, or rather, what Sony has suggested they do, whatever.
There's no doubt that GT Sport will probably win the sales and possibly the critical reception war considering it's massive fandom, install base, and history behind it. What is the true test will be whether or not the players that buy the game retain the game, and what the online looks like 5, 10 months to a year from release. Believe me, when the casual sim player gets a hold of the game and sees the lack of single player content, and gets bored quickly with the online racing, there's going to be a lot of angry people. And that is usually what changes things.
