They didn't cut any corners. It costs money to de-content parts and then stock new/different parts, etc. The plastic outer tubs have been present in DDs from the start, and are injection molded. They cannot be made with less material unless a whole new mold is built (at a cost of hundreds of thousands of dollars or more). The part numbers of the components used on these machines are the same as always for gearcases, tubs, baskets, etc. The price is low because the tooling has been amortized and fully depreciated, the line in the plant is not yet converted to the VMW so they need something to fill the capacity, and the DD washer, still made by the tens of thousands, has always had a high degree of mark-up, so they are simply selling for less. You should really check your facts before you become such a nay-sayer, at least when offering advice.
As to when production ends, I was told either end of this month, or end of April. I think end of April.
About the rinse level switch -- it is not as simple as taking out the rinse pressure switch. The wiring to it would have to be meshed with the wiring to the wash pressure switch in order for proper circuits to be satisfied, and even then without experimenting/seeing a machine, I don't know what other things should be jumped to be safe, etc. Best bet is to install a pressure switch for wash from Whirlpool's recent WTW5100 (then you'll get a full wash fill) and set the rinse at full fill provided by the current switch, OR install a single level DD pressure switch in its place which provides a full fill. I wouldn't modify electrical wiring unless you are comfortable and feel safe doing so.
