Well I think 1 year is more relevant than 2 years, but whatever. PvP has gotten in the last 2 years Ancient Hypergates (Dec 2012), 3 Arena maps (Sept 2013), Another arena map (Dec 2013), Quesh Huttball (April 2014) which brings the total to 6.
For ops in the last 2 years we have SnV, TC, DF, and DP. So, 4.
