It's not to farfetched to think that perhaps that's when they feel they my release the game. Since they have it setup where players will be able to play on the servers til it drops down the 30% mark however they might as well just setup the max date they feel til 2.0 is released.

Current sched seems to be global alpha nov26, Beta sometime around Jan/feb, so a april/may release isn't to farfetched to consider. Odds are that by the end of march they may have open beta from april/may and then perhaps a june release. So that's another thing to consider is the end of march is when they may have open beta so why would people still want to play 1.0 when 2.0 open beta is active lol.
