Devs have said 10-12h if you rush it and if you play stealthy and do all side missions it's 15-20h.
I also think we can expect lots of new levels and mods very soon plus MP isn't too shabby either. There are already some very interesting levels in development at crymod.com. It's definitely worth it's money if you enjoy the game/gameplay.
