As we speak Eve is updating to Citadel, the new expansion that will bring the new POS like structures, or maybe as POS were originally intended 
. You can get your Medium, Large or XL structure blueprint at the moment and a select number of modules. I can imagine the sub components needed will sky rocket the prices in the market, but things will settle down eventually as they always do.
Meanwhile Blog Banter #74 is going at the moment. It’s about Fanfest and what people thought was the biggest reveal. Well I didn’t notice any. So I decided to not dedicate a post to it. But I felt obliged to post this here though, since I usually love the blog banters.
The official announcement blog post is over here.
