Difficult to say.
The most recent inflation stats from Eurostat are here:

The ECB's target is close to 2% HICP inflation.
You can see that HICP inflation in the EMU zone has crept up from 0.6% pa last April to 1.5% this April.
This suggests that if HICP inflation keeps rising, the ECB may act by increasing their rates.
Also, the weaker euro will cause import costs to rise, esp. energy costs.
However, the financial crisis and fiscal cutbacks mean econ activity is sluggish, so I don't think the ECB will increase rates until 2011.
