It was inevitable that there would be a Winter world cup sometime in our lifetime, so we better get used to the idea now. If Australia/NZ ever end up hosting a WC in the future, it will be winter as well.
Well our winter is Australia's summer and their country is right under the hole in the o-zone layer so the chances of making them play a world cup then would be slim to none. It would be held in our summer/their winter because then you'd have weather capable of playing football in
South Africa was the same
The summer World Cup in 2010 was actually in their winter as they are a southern hemisphere nation. So technically we have had a winter World Cup, it was just the winter of the host nation itself
