I queried Flipboard directly as it's my favorite app. Quite frankly, if I could get Flipboard on BlackBerry, I'd probably not even bother with Android or WP8, but I really love Flipboard. It's the primary reason I got an Android as a backup to my BlackBerry years ago.
No release date yet, but I have heard Rumors that November is the month. Let's hope.
An Agent from Flipboard responded as follows:
While we don’t have an exact release date, Flipboard is coming to Windows 8 later this year. Flipboard will be available both on Windows 8, and its mobile version, so you can enjoy Flipboard on all your Windows 8 enabled devices.
Thanks for all your requests. We have been listening and are exited to see all the great magazines Windows users will curate using Flipboard.
We will share more details about the full Flipboard on Windows experience closer to launch. For now, check out our blog post for some additional information, as well as a (short) sneak peak of what Flipboard will look like on Windows 8:
