That absolutely makes sense. It's like last season, they introduces the cast via TV Guide (the magazine) and on the TV Guide site. Not on TV Guide network.

SO I guess it will be on entertainment weekly magazine and the official site EW.com
Just so you know Dalton Ross the former host of Survivor Live is the current writer for Survivor and he went to Palau on November to see the first few days of production.

So it all makes sense.
