There is always hope, but generally speaking the chances of it going diminish with time and it seems that for most, it generally goes within about 6 months if it is going to (this is based on empirical evidence). Having said that, I have had tinnitus for a couple of years, and even now, it is slowly becoming quieter, month by month.
The trick is to not to let it rule your life. If you are going to really loud places, then you need to protect your ears, but normal, every down sound levels are good for your hearing - don't overprotect by trying to avoid all noises. Get on with living, eat well, get good sleep and you might be one of the lucky ones.
