Sorry to be off topic a bit but:
New Euro won't be till 2009:

Besides, going off the release of the Accord (Inspire) and its new engine, the new Euro would be lucky to have about a 20kw increase in power. It is just going to have the new A-VTEC 2.4 I4, still FWD. So I think the current model has far more potential for power gains as it has been around since 2003 and far more supported products are available. In term of modifying why wait for the new one, you'll be in the exact same position most euro owners were in when the car was released.
