We've seen some evidence that the next version of Windows Phone, code-named 'Mango' is going by 'Windows Phone 7.5' and that seems to yet again be confirmed.
The ReMIX11 event, happeing in Australia June 1-2, has their page up and registration is now available. But what's interesting is the reference again to Windows Phone 7.5 in the talk by Shane Morris & Nick Randolph called 'Real world Windows Phone 7.5'. Though we shouldn't be shocked that Microsoft wants to share more about 'Mango' (it's a pretty huge update), we are hoping some new info comes out as the milestones/feature set is locked in.
Now lets see if Microsoft amends the '7.5' reference here like they did on that Microsoft Partner Network site, ahem.
Update: Don't expect anything new on 'Mango', as Shane Morris & Nick Randolph are responsible for the Qantas app demoed during MIX11. Thanks, Chris Walsh, for the clarification
