Not to snark too much, but he idea of renegade 4J coders having created the Mash Ups with out permission and are now waiting on a sign off is hilarious. Every software job I have ever had, big or small, Legal always on the ball from day one, and man, you'd better not sneeze without their approval.
I am sure games are different, and probably some goofy non-compete clause being checked or something, but I choose to believe they made it and waited until it was done to see if t was cool thinking apologizing is easier than asking permission.
I'm pretty sure Mojang and 4J would like to release these things for free
"Microsoft has been known to require developers to charge for their content, when the developers would rather release their content for free. Some content has even been withheld from release because the developer refused to charge the amount Microsoft required. Epic Games, known for continual support of their older titles with downloadable updates, believed that releasing downloadable content over the course of a game's lifetime helped increase sales throughout, and had succeeded well with that business-model in the past, but was required to implement fees for downloads when releasing content for their Microsoft-published game, Gears of War."
Obviously they would like to release things for free. Just because it's sony does not mean they won't make them require a price as well. Look at how well skinpacks have sold, Sony would be fools to not see the numbers. Like I said above, Sony is a company too; they're not these massive gamer lovers that PS3 fans make them out to be. Every company is greedy and rightfully so. Sony know how much MS has made off MC:XBL and it's DLC's and will not turn down that much money. End of.
