most people on ET think the dollar is dropping out with no low in sight. Most analysts think 1.65 ish will see intervention by G7 countries.
I say look to the ECB when they change their "inflation is everything statements", THEN look for reverse in trend.
personally, i think its sooner rather than later. GBP and CAN have topped vs the $, and maybe JPY soon too. GBP is also at record lows vs the Euro due to the same reasons as the US more or less.
