Not all of us have a Halloween Skin pack. I am a huge Halloween geek and would love more Halloween themed things for Minecraft everything in my life.
Unfortunately, last year when the theme pack came out I did not have internet (I had just moved and had not connected it) so I wasn't even aware of it's exsistance until this summer. I would love an opportunity to get it (though I doubt that will happen as I read it was limited edition) but I will be equally happy to get anything Halloween themed for Minecraft. I'd even settle for a useless Hallowween themed Minecraft Theme for my XBox dash
It will be cool and all but what happens when you start playing on Xbox One? Would you be somehow able to transfer the Halloween skin pack across or wait all year until they do another limited edition release.
... and that's the main reason why I can't see why they wouldn't release it again. There is no time frame or limited edition if it's for a good cause.
The reason it (PROBABLY) won't be released again is because of legal stuff and paperwork. When they released the halloween skin pack they had to do legal stuff and paperwork from all three sides (The charity, 4J, and Microsoft). They probably don't want to go through all of that again. That's why they released the free texture pack. It's alot easier to release something free than to do all of the paperwork over again. But don't get me wrong I'm not trying to prove you wrong or anything. I just want to clear it up
