Giving this thread a nudge as it is going to be release in May. I have looked at some of the recent footage and though it looks a bit janky it is looking like it could be great fun.
There are 3 zones, 1 which is kind of starter friendly, 1 which is then PvE and bigger in scope and then an end game one which then include's the PvP element. The discussion around the PvP area is that because it is a whole bunch of servers all meshed together you could potentially have up to 900 players in this larger end game area at any one time and it appears to take some influence from Battlefield and Planetside games.
Definately one I will be giving a try I think.
