The screeny i posted was created by just visiting the store and than the backbutton.
I just remember, between the Preview and just before the Black roled out, there was a other update from MS.
Maybe they resolved the issues in that update.
We dont know if MS wil follow that same path again, and there is no choice than to whait and see wat happends.
I would advice to be cautious, and wait for the first results.
Mayby beeing selfish, but i rather wait a day and read about some issues and hopefully solutions .
then be the first one who has to report about having those issues.
