I also agree actually that content can be released as it is. (VWS, Rockingham & ??)
And than later the rest could come.
Release it as a new version, let people pay for it, let them get excited!
Let new activity come to LFS, as there where people who bought S2 with the promise of VWS coming soon, and they bought it for that reason.
Now when Patch Z25 was released, I can remember something in the message like:
"And we'll do our best to get the Volkswagen Scirocco and the new tyre physics to you as soon as possible"
However, that is more kind of a lie.
It seems that LFS Devs are now working on a full S3 package, with lots of new things.
On one side this is great, but on the other side, they did not full fill their promise, which brought the community to a new low.
I think that all we need is a complete new track & car, in some sort of open beta, until S3 comes out.
This to keep people interested, and giving a positive look.
