I mean seriously, cutting down on content will cause so much outrage and backlash from the community and die-hard fans, myself included. That is why, in my opinion, Motorsport 8 should probably launch with an even larger number of cars than what Motorsport 7 has in its final form. If it can reach over 1,000 cars, given the new additions from Horizon 4, as well as the re-introduction of Lexus, Toyota and Scion, it wouldn't be that impossible, and would actually be great for this upcoming game.
As much as people want to recreate the feel of actual racing, there also has to be a factor of having cars that will cater to everyone's tastes. Like me, I do love me some good race cars, but I also kind of like some variety and fun in between with the cars I see in a Motorsport game.
The Motorsport games are all about offering a realistic driving experience whilst retaining the massive car lists from across all the titles, so that there is always something for everyone, even the odd-ball cars. The newly-redesigned physics can even open up possibilities for certain types of cars as well.
Who wants plenty of cars to be left out where the variety of cars we've experienced would be completely gone? Does that mean we will experience a scenario similar to Motorsport 5 all over again?
Having to cut down on the car count for Motorsport 8 would be absolutely unreasonable and totally horrific, and despite the new changes, it will really seem like a step backward. I don't know why some people here think it's a good thing where it really isn't, even if they would think this would be under the guise of "quality over quantity".
All the cars in Motorsport 7 are built exactly in the same graphical quality, and all they need for it to be on the Series X is a minor graphical polish and the new ray-tracing features. And besides, it is highly likely that Motorsport 8 would still be an Xbox One title, with an enhanced Series X version with all the bells and whistles that make it so (hopefully it will support "smart delivery").
While I do love the improvements such as the newly-redesigned physics geared towards realism, dynamic time of day and weather on all tracks and off-road/rally racing, the car count should not be cut down at all.
