Personally, I think the Devs are working hard, on something, at least, I cant be specific because I am just guessing.... but definatly working towards a possible final version of S2, whether that be a beta stage or even a total rework of the sim itself.
This is not a critisism, and like the OP, this is just my opinion, occasionally the devs have something up there sleeve, and they have never failed to dissapoint. Many times over the years, and I have been with LFS from the start, suprises have come, in the forms of sublte changes, to massive unexpected updates. They may even be distracted from the development of the game, for commercial progress, using the platform as it stands.
I just hope they are actually working on it, and not completly pished off by those who demand, cry, winge, bitch about updates not coming out.
