According to Allpar.com, it eliminates the second row Stow-n-Go seats, not the 3rd row, which is a shame but IMO, not a deal-breaker. Removing the 2nd row is a pain but we probably do it maybe once or twice per year in our minivan so I wouldn’t pass up significantly better mileage just because I lose a neat feature…

There isn’t much information available on it yet but it sounds like the Chrysler will have a removable 8th “jumper” seat available that goes in the second row. As far as 28mpg, I’m not sure which model you are referring to but we have a Sienna and had a Sedona and both average around 18mpg combined.
