The Java version of Minecraft has sold 20 million copies as of last week. Pocket Edition is already much bigger than the Java version, by the way.

Checchi added that Mojang is aiming for feature parity across all Minecraft versions, though the Windows 10 version won't support Minecraft's lively modding scene for now because "C++ is not as reverse engineerable as Java, plus many stores don't allow those kind of mods." In addition, even if the Windows 10 version did support mods, the modding community would have to remake all of its existing Java work in C++.
