Xenoblade sold 83k copies during its week of release in Japan, but 6 months later, it only managed to sell an additional 78k copies. While the game was considered a success by Reggie (of course, he didn't tell us the sales so it can't be that impressive), I doubt it will be enough for NOA to automatically localize "X". I mean, Xenoblade's success will likely be a factor in contributing to NOA's decision, but "X" is coming to a new platform with a much smaller install base compared to the global sales of Wii U in 2011-2012. In addition, "X" likely is a more expensive project than Xenoblade just due to HD development costs. The average Wii game has been said to cost around $5-7 million according to research firm, Ibis Capital, whereas HD development for an average title was estimated at $15-30 million.
