Some brokers are now beginning to quote the other major currencies to 5 decimal places. So it appears likely the pip will stay at 0.0001 units for most currencies. Most traders record their profit and loss in currency trading pips as well as in money. This enables easy comparison of one trade with another so you can appraise a system. It also suggests that traders can discuss their leads to a foreign exchange forum without unveiling the scale of their account or their profits in greenbacks and cents.
