Well, based on the previous release rate, I would have assumed the UK would get another double issue last month but I don't know the new release rate and the only place I know to check for UK releases http://titanmagazines.co.uk/app?service=external/Product&sp=l104
is still the first double issue. Perhaps it will be a triple issue in June?
As for the Australian releases, I'm thinking about a redesign, perhaps we should have that information there, if it can be tracked down. I can dig some out of the edit history, the oldest ones I might find in Wikipedia's history if it was there at some point.
