A new review on exoplanet demographics, written by Scott Gaudi, Jessie Christiansen, and Michael Meyer was posted this on astro-ph this week to coincide with the Exoplanets Demographics conference held at the NASA Exoplanet Science Institute (see previous post).  Shown here is one of the figures from the paper summarizing recent results.  The main focus of the article is to list key questions and future prospects for progress:  there is a lot of exciting work to do in the coming years!
