I expect to see a huge influx of old players that have been gone but regarding new players, not so much...
Also they will go away again when notice the game is in the same state as February 2012 (maybe worse if we talk about PVP) and leave again in 15-30 days.
We will see queues? Maybe , my bet is first week 35% of returned players 10% new tryers.
will we see new long term players?... with this deluxe trial...No.
