If you weren't here for 3.1 then you have absolutely no idea what a true zero content patch looks like, just saying.

More serious answer, it's a catch up patch, they've always been thin on content. Yeah they might be spacing out releases, but why is it such a big deal? You'll only be done with it in a matter of days then sit and complain about nothing to do. Take up crafting and gathering, we have lots to do this patch. That might not be "content" in your eyes but it is something to do. Worst case scenario, just stop playing the game for a while until the content you like doing comes out.
