One question I could not answer is now answered, Israel it seems will be very welcome at 2022.
There is always meaning to Fifa's madness, and that is why do the two bids for 2018 and 2022 together? and I think I know the answer. With the new international calender pretty much now set in stone, there is an opportunity to try and get the leagues to have and earlier start to the 2022 season (and a later end) and play the World cup in December/January when the conditions are better, in what is for most leagues are the mid-winter break.
Having a 12 year lead up time gives you time to get organised. It was always going to be Qatar that's for sure.
