Sprint's Samsung Epic 4G and Sanyo Zio signed up for Froyo next week?

We've been tipped with a document today that seems to suggest that the age of Android 2.2 is nigh for owners of Sprint's Samsung Epic 4G and Sanyo Zio. The Epic's looking like a four-day phased rollout to build EB13, while the Zio push spans five days (strangely, it says you'll end up on Eclair build DF05, which clearly isn't accurate, so we're hoping this is just a miss by whomever created it). Both are said to kick off next Monday, the 21st -- and for Epic owners in particular, it's a long time coming. Best of luck, folks.
