We are unsure really as Craig, the GD has stated "We will release no patch before it's time" being dev speak for "STFU and let us finish it".
But, we can at least get an estimate based on the current release schedules of the patches hitting live in the 1.04 series.
Today 1.04.7 hits live.
I think a countdown to 1.04.9 could take place before we see final. But again that has NOT always been the case...1.03 had 5 releases before 1.04 hit due to demand.
With the new content and new trials in place, I am sure they will not take any chances though.
Someone stated June in my comments, and this could be possible.
Lets look at some other criteria.
We could have at least 2 more patches, so two weeks of patching to be done. But, that only takes us to May.
They started offering 7 day trials. Then the hope is the 7 day trials will turn into 30 day players.
I think the two patches will be released, then a 30 day moratorium on patches to allow these new players to get acclimated before htitting them with an NGE (I mean the changes are drastic enough to warant the NGE title. Luckily it is not a game destroying altercation.)
Any other theories?
I call end of May / Early June to see the new systems in place.
Ok...well, I am off..I have one hour to play then major dental surgery (for the morbid, look up post core dentistry to see the procedure...nothing like drilling and placing spikes into my head)
