What I know is that the Hybrid 2007 is actually getting the new front (headlights) and rear (tail lights) from the Japanese Civic Hybrid 2006, and if you ask me it looks way much better (the Japanese version) than the US version.

Apart from that, the Hybrid is going to remain exactly the same.

Oh BTW I know this because the PR Manager from Honda here in Mexico told me so and I think its a reliable source of information.
