We wait.............
I think one of the problems of hanging around on tech forums is we hear snippets, gossip, advance details of release dates and we loose patience, it shouldn't be too long though.
Please note that it is Microsoft who release the firmware not the separate company called Nokia, Microsoft bought the device making division of Nokia many months ago now, so although most of the current phones still have a Nokia badge on them, they are in fact Microsoft phones and all the development of software that we call WP is done by MS. Nokia as a separate company make software like Here Maps and some others software but no longer make phones.
