Give 'em a break dudes.
Westhill update is being prepared
now.
S3 is somewhere in the future. And that future is not "near" in terms of digitally released games in these days, so there's little point to ask for some peek into it, because it may change dramatically over time.
Once they will be two weeks before S3 release, I think they will do some announcement. Then you will have several months to speculate, guess, comment, ask for test builds and wonder how long two weeks may take...
Really, what should he write you now? He has hard time foresee all the details which will happen just in the next build. S3 will be huge when compared to single track update, so let the future sort out what it will include.
I'm already very happy with the simulation aspects of LFS, but when I compare it to my real life experience with karting and endurance races, it has plenty of room for improvements and additions, so I'm really looking for S3 taking it several steps ahead, to completely new level of experience. Whatever development time it will take (hopefully I will be still alive
).
