New content is always good so +1 but, its a big but so, BUT as already said there is improvements and changes to me made to other areas such as physics and AI not just the content of LFS. Yes more tracks would be good, either in a couple new combos or a whole new track. Whether we get any who knows, you would have to ask the devs directly.
The problem, which I feel gets overlooked, is that we have such a wide variety of cars from UF1 to BF1 for speed and LX to GTR's in weight. All of which have different characteristics and all of which suit different tracks. You wouldn't take a UF1 on a grand prix curcuit as would be too long, while you wouldn't take a formula 1 car on a little club track like fe club. To me I feel we have a range of tracks for each car so for bf1 we have aston gp, aston gt, ky gp and ky nat and you could include aston national, while for uf1 we have small south city and small fern bay etc etc.
But still more content +1 but personally i would rather have better physics and AI before tracks.
