Any word on system link?

Also, anyone want to give a run down of bullet points? (I don't want every feature, just major changes/selling points):

16 cars online
12 cars career
New challenge/nemesis feature
Online custom lobbies
New graphic engine

How many more tracks? I am hearing some things got toned down (like customization) and the lack of non-replay material is a hmmm

Most of the individual upgrades and tuning default parameters for each car have been slightly changed for this version based on changes to Automagic (the server-based simulation before the real-time simulation). But, the general system remains the same – same parts and same tunable setup parameters. Cars still cannot be tuned asymmetrically in the tune setup area. Car setups cannot be tuned in the lobby, just loaded. However, there have been four noteworthy additions to the upgrade system:


1.We’ve added various HEV (hybrid) and all-electric cars to the game. In order to enable the addition of these cars, we had to change the physics, audio, Automagic, as well as change the available upgrades. Based on what type of hybrid or electric car it is, and also what kind of transmission it comes with (i.e. CVT), the upgrade system gives you some new hybrid or electric-specific upgrades in the power section.

2.We’ve added a second level of “restrictors” upgrade, as well as some limited tire width options to most of the race cars. In Forza 3, the restrictor upgrade allowed you to remove restrictions on the breathing of the race cars. These new restrictor upgrades sit in-between stock restriction (set by the real-world governing body that licensed the given car) and fully unrestricted. These new levels were tuned to allow the car to get to the top of its stock class in combination with other upgrades such as tire width. In effect, this means that a car like the BMW V12 LMR is able to get to the top of R1 without going into X.

3.For Forza 4, we’ve added a drag racing tire compound. This tire compound has more accelerative peak grip than the racing slicks, but has extremely poor cornering characteristics. Frankly, this compound is horrible to drive on a road course, but launches like a rocket. This compound also wears much faster and reacts to heat differently than the other tires in the Pirelli dataset. Because Forza is an automotive sandbox, we allow you to use this tire in regular road racing--however, you’re probably going to want to change the “damage and wear” difficulty settings to cosmetic. With the proper tuning setup, we’ve been able to use these tires to get wheelstands, but it also requires strong clutch control and car with the “right” center of mass.

4.There have also been changes in the “Aero and Appearance” section of the Upgrade Shop. Most cars with distinct, standalone front and rear bumpers now offer an option to remove the bumpers. For a more period-correct look, specific models receive vintage motorsport-inspired front and rear aerodynamics, and add paintable headlight covers for a race-ready look. Some muscle cars now offer aftermarket drag racing style hood options in both Pro Stock and classic cowl-induction configurations. You’ll also have the ability remove the factory rear wing or spoiler from some cars, and for the ultimate upgrade, some cars allow you to purchase OEM appearance packages available only from the factory, completely transforming the look of your car. While not every car has each of these options, the new options and features are going to open up a new world of customization options for racers, painters, and photographers to experiment with.

Looks pretty good, I guess.
