Before it does so, lots of interesting things can happen but ultimately it's going to be cold and dark and motionless.
That is the likely outcome based on the information we currently have but it is not established fact yet, current estimates put matter at 5% of the universe, 35% dark matter and 60% dark energy which would lead to a continually expanding and dying universe but these sort of discoveries have the habit of being trumped with yet more information which gives a different answer. I reckon 10 years will give a more definative answer
