Previews is only another method to take it long and milk the supporters. If they are happy... I'm happy too.
Anyway, again the topic isn't IF the new version will be relaease (it will be) but WHEN and HOW.
When? -> Icstor isn't stupid. Yes, he is disonest and cheater but it's all calculated. He knows he can make a lot of money working 1% of the time and for a certain reason his supporters are agree with this (otherwise they would stop to pay him).
How? -> In my opinion this is the main topic. Maybe someone think or hope it will be a huge update. He worked many years (hahahaha) and sweared many times to have one million renders ready. No! It will be much less than what most expect (remember that pregnancy and harem paths has been cancelled). The feeling will be more or less the same as when the 0.71 version was released. Anything less than 10000 new renders would be insufficient.
If I'm wrong I will be here to admit it.
