I'd be tempted to get this just to save some space on my DVD shelf, to replace the individual boxsets I have of the three series... but then I'd be stuck with the US editions that would be impossible to sell at a reasonable price.

If this edition had the unreleased Energon episode (Scorponok's Scars, the most pivotal episode in a series that was weak on plot to begin with), I'd definitely all over it. Even if it was just a subtitled edition of the Japanese episode, it would make the series feel more complete, and make sense of a number of plot devices.
