Well, the lucky folks who play Minecraft on the XBOX now have the Simpons to run around as. 24 of them atleast, as well as the elementary school, all included in the latest DLC pack, which you can get in the xbox marketplace for a mere 2.99. Or on XBOX Live for the XBOX One.
When will this be available for other platforms? Who knows. There is no official announcement and mums the words. As we can see, Minecraft belonging to Microsoft is really going to get things to those platforms more quickly. Not that it's Microsoft's fault, really. They can burn through the red tape much easier on their end, and not have to wait for other platforms approvals.
As always, when Minecon tickets are released, they go fast. Many people are without, and there is never a good way for them to be released. There are just too many people who want to go. So you can blame Mojang for whatever method they use to dispense the tickets, it just won't work, so might as well resolve yourself to that.
What do we know besides they will be difficult to come by? Here are a vew tweets from the COO Vu Bui:
There will be advanced notice before the MINECON tickets go on sale, they won't go up right after we announce, so you'll have time to prep!
So, really, no information, besides they are coming, but then again, we all knew that already. Some things to keep in mind. Be prepared to be logged in to buy them. Be prepared to refresh (might have 2 browser windows open, with one continually refreshing and the other just waiting - if there is some count down mechanic. Try to order them from the best network possible. Potentially your work or school? Have your logins ready for Minecraft / Mojang. Hell, I'd even be ready for something like ticket master or eventbrite just to be safe! Good luck!
