Because of the following statements, from the man himself;
"I want to reveal today that we are adding SGR with some NPCs on Makeb and do intend on pursuing more SGR options in the future."
So there's your "SGR" offering, coming in spring.
As for world pvp, you know a standard mmo feature (offered by every other mmo on the market, in the past, present and future)... well yeah;
"do not look for massive new Open World PvP this year"
That's a hell of a statement to make in January, which to be fair I'm thankful for because I now know that they won't be seeing my subscription fee this calender year.
