I'd bet -
the same size as the current Elite I. Simply put - with each of the four molds that it take to make any Oliver costing in excess of $2,000,000 (i.e. total cost would be in excess of $8,000,000) the cost of introducing a third size of travel trailer is simply too high. I'd also bet that similar to what has been done with the Elite II, a different model and/or trim level for the existing Elite I is behind that cover in the pic.
