I posted on Morgan Stanley's European Central Bank preview here a little earlier:

And, also, earlier previews from about the place are here:

Anyway, here is MS again, this time with ... A word on FX:

  • Most ECB speakers have tended to lean on the hawkish side recently.
  • We believe that their view is already well known in the marketplace.
  • The press conference and Q&A this Thursday will likely be more balanced, to reflect the broader opinions within the Governing Council.
  • Some of its members highlighted the risks around the recent FX uptrend. Beyond this level and pace of appreciation it could indeed become a key factor to watch - though the rise in oil prices still points to upside risks to the ECB inflation forecast.

(bolding mine ... you can see MS is wary of ECB expressions of concern on the euro strength, which is a (not unexpected) risk for the longs)
