I have signed up (of course) and suggest anyone here wanting the live feeds, do it before the early bird cut-off of June 25th. You can sign up directly at the CBS website or various websites dedicated to the show. Since I know Hamsterwatch is a one woman effort, if you check out her site and sign up via the link she has there, she earns money. Alas, I don't have such a set-up for this blog. (If I did, I'd be asking you to sign up here!)
As in previous seasons, once the live feeds start, I'll be posting condensed versions (or stuff I really found interesting) of the live feeds two to three times a day, screen caps, coverage of endurance comps, blog parties on show nights and such as I have in the past. Supposedly, some content -- although not the live feeds per se -- will start on the feeds on June 11th. That should probably be the media day coverage during which various web writers do a mock-up of an eviction in the actual new house.
The season premiere is June 26. The cast won't be announced for a while yet. They're usually in the house four or five days before the premiere to give the producers film fodder for said premiere. They're usually in sequester for about a week before they go into the house. So, I'm thinking cast reveals should be around the 15th, give or take a day or two.
