We had quite a lengthy discussion on the subject of 230/240V kitchen appliances in the US a few months ago I think and I was referring to that thread. Some posters jokingly indicated such practices were going to become more and more common and I just continued down that path

It might happen - many European countries once used 127V three phase distribution. Over the years, more and more appliances were connected phase to phase and eventually the power companies stopped providing 127V altogether. The same thing might happen if 240V 15 amp receptacles in the US become widespread enough and the chinese manufacturers decide to import only 230V gear any more.
