Hmmm... and there will be a Windows Phone Developers Summit in June.

IF they are going to talk about the Apollo, and IF Apollo has something to do with Win8/WinRT, they  should talk about them together, at BUILD, right ?

BTW, the lastest rumor about Apollo is, the dev tool for Apollo requires Win8 RP to run, so the date of WPDevSummit (20 June) will be perfect for Apollo announcement because Win8 RP  ("1st week of June") will be available at that time.
