Let's talk about facts. We don't have big new content for more than a year. We are waiting for the "real" patch for too long and it's getting boring. The good thing is, that we don't have to pay for next patch, but I don't care too much about the money in that case.
For me, I have to say waiting has a limit and I will have some fun with other simulations (iRacing and so on). There is more development going on there. That doesn't mean I will stop playing LFS, but I don't know what will be in the future.
