a) they ALREADY have ported to C++ [ see MCPE for details ]
b] they are generating tons of profit - well, sales - from the C++ version, not from the Java version
c) killing modding won't touch the sides of the overall sales, but it will reduce the cost of controlling it
d) killing the java version will reduce cost overheads - as they won't have to support multiple platforms [java and C++] and will leverage the Win platform, just that alone will raise their share prices as it ties people into their platforms
e) why would a programming team have any say in marketing strategy? that's never happened at any software house i've worked at
I didn't know about the C++ version of Pocket Edition (never even played it), so I'll give you that. (Thanks for the info ) But I have to disagree with you on the modding bit. I know personally that many of my friends have bought Minecraft for the sole purpose of playing some of the fun online servers like Mineplex and Lichcraft. These servers are made up of many different Bukkit mods, and would never have been as fun if they had no mods. Vanilla Minecraft is very boring compared to some of the things you can do with mods. Had Bukkit not been around at the time that those friends bought the game, the chances that they would have still bought the game are pretty slim. I know that mods have contributed to sales, and obviously the Bukkit staff knew too, what with many of them quitting because they felt cheated by Mojang.
Also, I'm not speaking of only the programming team. Mojang has obviously been doing something right this entire time to make themselves worth $2.5B, and it would make no sense at all for Microsoft to jump right in, kick all the experienced know-how people out, and replace them with random employees who think they "know better." If Microsoft is smart, they would let the Mojang staff continue to do their thing, maybe lay down some new ground rules, and slowly begin to merge in new ideas. I highly doubt they would pop in some new features and marketing plans without at least getting an opinion from the people who made the game what it is today.
