I too would love to see Plex support asap, though It appears the original article was a little generous with their "fall" estimate. Still no official word. But the Plex devs usually keep a pretty tight lid on things until they're ready (or able, if Google has them holding it) to release new features.
Release could be hours away, it could be months away. I just know I'll be thrilled when it does arrive.
Thankfully, I can be pretty patient. And having some free Netflix in the meantime doesn't hurt.
