Also, this from the Wall Street Journal in their popular '5 things to watch' format:
1. Look for Mr. Draghi to be pressed on China's slowdown, the euro's recent rise and weak commodity prices ... all of which point to near-zero inflation in coming months.
2. ECB staff's economic and inflation forecasts ... will be more significant... particularly the forecast for inflation
3. If the ECB refrains from new measures, Mr. Draghi's hints on future steps will be key.
4. EUR/USD ... Thursday's press conference gives Mr. Draghi a chance to underscore the divergent monetary policies between the ECB and the Federal Reserve.
