I'm interested in knowing what the dimensions are on the 2018, whether it's a little shorter and wider...visually, it seems to be.
We have a 2005 Odyssey with about 175,000 miles on it and have had no significant issues with it. We've been waiting to see the 2018 so we could decide whether we should wait to replace our current one with the current generation or the 2018. Although I could live with the look/options of the current generation, my wife likes the look of the new one. I'd also be interested in measuring the interior noise of this new one compared to our 2005 to see just how improved it is.
The bottom line is, we keep our primary vehicles for the long haul, so I guess it makes sense to just go with the 2018 in maybe another year.
