Just landed on the Adidas Store site is a range of football shirts focusing on past hosts of the World Cup. It's called the Adidas Retro Jersey range.
As far as we can see, the shirts in the range feature England, Germany, Italy, Argentina, Brazil, Spain, France and Mexico. Not sure why some make the cut and other don't, but presume it's a commercial decision. Also, although the designs mimic classic shirts and eras, they aren't necessarily replicas – England certainly hasn't been on the Adidas books in a tournament (and as such, is the weakest design here).
But overall, they are nice looking things and probably preferable to the replicas on the shelves in time for the World Cup. If you want one, prices start at £40 online. Of course, if you want other eras or nations, you can always try the TOFFS website.
