i'd guess it means that whilst the price of oil is high, other sources of oil will come on stream. this may undermine the power of OPEC a little (but not a lot- the oil companies have a vested interest in high oil prices), if supply/demand theory holds. however as its managed supply/demand i don't see the price fluctuating too much. also if the price dropped, the extraction of oil sands would become uneconomic, leading to supply issues hence price rises etc.

re: the dystopian future thing- global warming seems to be a far more important issue than the end of oil.
