BW has told us plenty. You need to goto cantina events or watch the twitch streams! Eric Musco has revealed nearly everything. The only thing I haven't heard about is PVP and new Warzones.
It's 2015, stop living in the past. News is now carried by video shorts, live streams, and collaborative Q&A video sessions. Interaction via the comments section, twitter, and Facebook.
Blogs are like AOL chatrooms. NOBODY; except those living under a rock use them.
