I think Zelda TP on Gamecube might sell the 0.8 modifier you're applying, which would mean it would have to sell 573,800 outside of NA. But I don't expect the GC version to sell much more than that figure so I think it should stand at its current DKP of 148. JA has already shown lukewarm interest in the Wii version, based on the older article about the downward trend in Zelda titles in JA. http://www.vgcharts.org/news/news.php?id=59
