The vehicles identified by Fukui as being the likely recipients of a V6 diesel are the Ridgeline pickup, Pilot SUV and Odyssey minivan, with Acura's MDX also being a candidate for oil-burning power.
The V6 engine is currently under development and will likely debut sometime after Honda introduces their 2.2-liter diesel in 2009.
Another interesting tidbit from Fukui's interview with AN was his comment about the possibility of future Honda vehicles receiving turbocharged mills. He indicated that the introduction of the turbo'd Acura RDX did not mean that only the high-end automaker would benefit from the glories of forced induction. We'd like to see a factory-blown version of the Honda Remix come out by the end of the decade, but we're not going to start saving up yet.
